If you wanna brush up on your role playing skillz then I suggest checking the following sites out. And it's not just for brushing up, but there are some interesting tidbits of information on each.
http://www.coloryourprofyle.com/phade/alt.htmlNot really a "role play" help site, this site has alt codes that help you to make funny little characters like ¿ ƒ and the ever popular ©
http://www.freewebs.com/dember/RP.htmlThis site covers all the basics of role playing, and I greatly appreciate Dember for making such a wonderful site. It also has all the fake and real definitions of wolf script, you know, words like fae and brute, crown, that sort of stuff. I suggest that any beginner goes here for their start.
http://petpages.neopets.com/~_Navinia_Wolf role playing help site (or rather, pet page) that goes through all the basics of creating a character, as well as creating an introduction. This site has helped me multiple times with introductions, and it isn't just for wolves. You can apply this to any of your characters, as well as any post, not just introductions, because it deals with adjectives, adverbs, verbs, nouns, all that funny little grammar stuff that most people don't really care about, but what really makes a post amazing.
