1. Of course, you have to pick a wrestler. For a beginner it is a good idea to pick a main event superstar, who is very good on the mic and cuts lots of promos. If you get stuck go watch some promos of that wrestler on youtube.
2. Make your posts at least three sentences long, then work your way into getting better.
3. Try to stay in character. don't go around saying things that the character wouldn't say. i.e. having Shelton Benjamin go around telling people to suck it. (Joey!) That its out of character and is for DX. Same with other catchphrases unless your clearly mocking them.
4. Stay active. Try to post a couple times a day. If you don't stay active your going to lose.
5. Try not to bring up old WWE storylines. We are not trying to be the WWE. i.e. Don't bring up how Edge doesn't really love Vicki Guerrero.
If you follow these guidlines you will soon be a superstar!
