Johnny, if I may be so bold as to give you more advice:
Don't use "chatspeak." In other words, don't use the letter "u" for the word "you" or the letter "r" for the word "are." Yes, some people are used to typing quickly in that form of shorthand, but it's unprofessional. (It's also annoying as hell to many, one of whom I happen to be.)
Use smilies. It's not easy to make sure that your meaning comes across in this medium.
Look at the difference:
"I think you're silly." (OK, that just lying there could be easily construed as an insult.)
"I think you're silly.
" (Now we have "I think you're silly...and I LIKE IT!")
Sorry for the feeble example, but it's early.
Your posts regarding the radio show are "commercials" for the show. Make them enticing, make them funny, make them appealing, personalize them for the board...when in doubt, call a writer. (I know some!)
If all else fails, toss in Kirby the Carrot:
