I go back for spelling and grammatical errors sometimes, but those of you that have read my posts throughly enough know I don't do that very often.

I tend to be indecisive about my smilies so sometimes I'll go back and change the smilie if I don't think I've depicted the right emotion.

Because those are usually the only reasons I ever edit my posts, I tend not eo specify. There are exceptions though, such as when I'm posting in the FF forums and I've forgotton to say something about beating a certain boss or whatever.
