Here are a few "Do's and Dont's" on roleplaying! Of course, these are only a few basic things! Please feel free to comment on this thread with your own!
Do:
Include lots of description and comparisons in your posts.
Use dialogue that other people can understand.
Include movement such as walking, drinking, smelling, etc.
Use your character's five senses.
Describe the surrounding environment.
Research before you post. If you are responding to a particular topic, learn about it before you just make something up.
Follow the guidelines of the universe in which you are posting.
Remember to use good grammar, punctuation, and spelling. It is appreciated.
Think of creative titles for your threads...they are more likely to attract others to come post.
Be realistic.
Use links to pictures rather than including the images in your post. People appreciate not having to wait for them to load.
Chose an avatar for your character quickly. Avatars really do have a lot to do with how much "action" your character can get from other players. If no one knows what you look like, they really don't think about you.
Don't:
Take an insult to your character personally. It is just a character, insulting another character...that is all.
Use less than 6-8 sentences per post. While they don't have to be novels, less than that and you border the "one-liner" category once more.
Break the rules of the universe in which you are role playing.
Think your character is invincible. If they are, then they aren't a very good character. No one wants to role play with a god, especially if they always have to be right.
Post song lyrics unless your character (as in ~you~) wrote them. It chews up space and drives others nuts. And in most cases, they don't even read them, just skip over them to the other parts.
Use large pictures for your signature. Some people still have dial-up and it takes time to load those large pictures.
Get mad if you don’t get a boyfriend/girlfriend right away. The boards aren't meant as a dating service. RP romance is more than acceptable, but it takes more than 5 minutes of talking for people to fall in love.
