Post a motivational poster (one that's NOT in the Matt Foley Topic in Anime Screencaps) that you made. If it makes me laugh/cry/throw up, then you'll get a free opinion, no questions asked.
Here's a nifty site for making them if you're interested.

Oh, I do have ONE requirement. I can't take WMV as a file type. I also don't want any videos with sex in them. Hentai is fine, just no sex. :O
As for the opinion length, they'll be medium-long, and done in a timely fashion.
Post as many posters as you want, and I'll pick the top ten to give opinions to.
