I need a tagboard or chatter box for my site. I have tried flooble.com, myshoutbox.com, and tag-board.com. I really like tag-board.com, but it says it costs 20 bucks and I don't want to pay that for a tagboard. Are there any others?

I thought that that was for other features.. I didn't know they made everyone pay for either plan :confusion You could try c-box or something.
I think there's a free account one here: http://cbox.co.za/

EDIT: There is a free account at tag-board.com. Select a basic account when you go to register.

There is a free tag board at www.tag-board.com I do believe it was when I used mine.

**Edit** Oh wait a minute...are you wanting like lots of good features? Because it's not going to cost you 20 dollars to get the tag board, because they have two kinds Basic and Premium. That will cost you $20 .

Yeah, I use tag-board.com and the basic is nifty enough for me. There are a few basic features that come with it, but, if you feel like sifting thru the code, you can really do some good editing to it to make it match your page!

there's Flooble: http://chatter.flooble.com
