Guys I'm wondering if it is possible to move a forum from a host to another without losing datas of it, I mean I dont wanna do everything back again. And I dont wanna lose my members...Is it possible?

if possible can you give me a free host that's giving me everything I need for forum wich doesnt block chmod or anything for the forum?

Guys I'm wondering if it is possible to move a forum from a host to another without losing datas of itYup. A forum is just a bunch of files sitting on the server's hard drive. You can do a full backup of the files, then restore them to a new server.

Sorry, I don't know anything about free hosting.

As darnoldy says, it's quite easy. vBulletin has manual pages here: http://www.vbulletin.com/docs/html/moving_servers

For free hosts, try http://www.freewebspace.net/
