As a courtesy to your fellow posters, we ask that you please read the following suggestions (by Gina Trapani--with added comments by the GLITTER forum moderators) on proper posting etiquette. Why? Because there are a lot of people here and you don't want to tick them (or the moderators) off.

PROPER POSTING ETIQUETTE (YES THERE IS SUCH A THING)

Leaving a comment on a forum is like walking into someone's living room and joining in on a conversation. As in real life, online there are some people who are a pleasure to converse with, and some who are not.

Stay on topic.
Seriously. Don’t change the subject. Don't "threadjack." Don't post about tape dispensers in the Kristin Chat folder. There’s nothing more annoying than seeing a comment on a post about Kristin's latest role on Broadway that reads, “By the way, do you know anything about turtles?”

Contribute new information to the discussion.
Twelve people saying the same exact thing in one comment thread is useless and irritating. Before you comment, read the entire thread and make sure your comment offers something new to the conversation. If you don’t have the time or patience to read an entire thread, then don’t comment at all. The longer a comment thread the more likely someone has already said what you’re thinking, and the less likely it is to be read by future visitors anyway.

Don’t comment for the sake of commenting.
Posters who only say “Thanks!” or “totally agreed!” on an open thread have no business hitting that “Post” button at all. Did you like Kristin's gown from the SAG awards? Did you hate Kristin's gown from the SAG awards? Did you wear the same gown from the SAG awards to the grocery store a few days earlier? Whatever it is, say something of substance. Don't spam the forum with one word posts. Useless comments will gain you the reputation for being a useless commenter. Know when to comment and when to e-mail.

A forum comment is a public one-to-many communication within the context of a post. An e-mail is a private interaction.
I don't think we can stress this enough. If you want to have a private conversation about soy mocha decaf lattes, take it to email. Seriously. A comment that reads, “Oh yeah, that link is cool. By the way, was that you I saw in Starbucks the other day?” doesn’t contribute to the public conversation and belongs in an e-mail message to the author instead.

Remember that nobody likes a know-it-all.
The best kind of comments come from thoughtful, knowledgeable people who add more information about a topic. Know-it-all snark will go over as well on this forum as it would in our living room. Expect to get shown the door in the form of the delete button if you tell us that in real life, there is nobody under five-foot eleven in the White House--or other such annoying and probably-totally-false tidbits that are only meant to start fights. When fact-checking, pointing out a typo or dead link or expressing a dissenting opinion, do it in a respectful, friendly way.

Make the tone of your message clear.
No one can hear the tone of your voice or see your facial expression online. Sarcasm, in-jokes, nasty words, and exaggerations can easily be taken the wrong way in a public forum. Remember that a simple colon and a parentheses can change the meaning of a sentence entirely. Use emoticons or additional information to communicate the spirit of your message.

Be courteous.
Chances are, something someone says in a comment or post is going to eventually piss you off. Even still, personal attacks are unacceptable, useless, and can quickly degrade a discussion into a third grade “Yo Mama is so fat!” flamefest. Don't start posts with words like "Uh," or "Um" or "Sorry, but..." Resist the urge, and be respectful and objective at all times.

Don’t post when you’re angry, upset, drunk or emotional.
If you're over 21, chances are you've done the "drunkdial" thing before. And chances are, unless it was your best friend on the other end, it didn't go over well. Keep that in mind here. There’s no taking back a published forum comment - once you post, it’s there for everyone to see and for Google to cache. Remember, you’re not going to show your best face in the heat of an emotional moment. If you find yourself angrily typing a message into someone’s blog comment box - STOP. Get up. Take a breath. Walk around. Give it a day. Revisit the thread when your head is clear.

Do not feed or tease the trolls.
No matter how many times we roll our eyes at them, there will always be annoying people who surf around the Internet and inject pointless vindictiveness into any available textarea. Don’t let the terrorists win. Do NOT acknowledge these people with refutations, disagreements or even a mention of their screen name. Report them to a moderator.
