Free Message Boards?

Are there any free, ONLINE message boards? I do not want to add a board to my/a site. I want a site where you can make your own there. I have found one, but it's only free for 30 days. I would love to pay for a great one or a make my own someday, but untill then....

Thanks for any info.

I don't know how great it is, or if this is exactly what you are looking for, but maybe you could try EZBOARD.

It appears to me that the boards are free, and ezboard.com is searchable so its easy for people to find your board.
