Free hosting for my invision board

Hello everyone, I am looking for hosts who can allow me to host my invision board(for games) for free. I searched the net but unable to get anywhere. Initially my board wont be that big and members will also be less (say 500). I think some basic requirements to host are Mysql, php, etc (sorry i am bit noob to such things).So any suggestions are welcomed.

And which board is better, Invision or vbulletin though I have taken Invision, just taking your opinion.

Try byethost, or hostsnake.

Go with InvisionFree if it's less than 500members, really. You won't find free good ones, only FTP access.
Try x10 Hosting?
