best FREE tagboard or similar?

I need to find a FREE tagboard or similar that runs through someone else's server and supplies own code (like at tag-board.com). I would use tag-board.com but it doesn't allow more than 200 characters per post. I want a free one that allows MUCH more than 200 characters per post.

Are there any? Please help!

(basically i need a tagboard with long posting, like a compact little forum or something that u can insert into your webpage)
