Well, you can use Fantastico to install, but if you try to move it to another folder, you have to edit the config_global.php
There you can edit the url of the board and then the board is working again in the new folder :lol:
But you just have to know that..

With the new Invision Board you can better install it in a folder like "forums" or "forum" because you can use the portal IpDynamicLite
You put the index.php in the root and the forum in the folder "forums" or "forum" and then you can use the portal with Invision Board which is not installed in the root..

Take a look at www.mbforums.org (it's no advertising!!) there you can see the portal..If you take a look at www.mbforums.org/forums then you see the forum..
So it's no problem that Fantastico isn't installing it in the root

PS: Do you still understand it? It's like "blah blah" when I read this post after writing it :lol:
