Oooh stats. Do they affect things in the way they would in Tabletop RPGs like D&D, or does it serve a different purpose, like simply illustrating how good a character is at certain things?

Also, I'm not used to applying to RPs on this forum (this is the first RP here that I plan on joining, I used to RP elsewhere), so I still don't know exactly where to post the application. Do I post it here, or do I post it as a reply to the character sheet?
