Well I came in during the days of scary bashing. I had a natural preference for proper spelling and half decent grammar. I guess that really helped. Plus the Antis were the ones doing that so, in my mind that registered them as not idiots.
Heh, I killed that, mostly, before I was even in MR fandom. Didn't fully kill being n00b until the old MR, but that's all deleted. >.<" My only huge issue on MXwas 1. Insulting the occasional person in debates. and 2. Grammar. Oh, jeez, I'm still horrid with it, but. . . *dies* If you go see the remaining of my posts on MX, especially the snippets you see pre-April '09. . . . x.x So. Many. Errors.
I don't think I was ever a n00b on the forums, and I only lurked before I posted. The first threads on the forum I read were Charlie's and Logic's arguments against the series, and I agreed with them before I posted. The worst thing I ever remember doing - posting-wise - was not capitalizing. Everything else I wrote was fine, I just didn't like to capitalize...
Yeah, I don't really remember.
EDIT: And I was a bit unnecessarily - er, I dunno how to put it - mean? - a little while after I became anti. Especially on the HP thread. Good times.
