That might be annoying for some people and I'm not sure how to add it every time you say something. I could, however, make a menu item which you can click to spell check what you're about to say.
oh... Quite a few things, eh? /Sig is just what I'm used to, will change that now. $sock().mark is still unfamiliar to me so I'll stay away from that for now. I'll get $nohtml in. I'll fix the unset %s* too. Thank you!
