I'm not so inclined by this idea, because from bad experience in the past with these forum hosters we know that it can turn out pretty badly. For instance when ezboard were hacked, we lost most of our posts and they were not recoverable. I won't go for this solution when there is no easy way of backing up the posts and no feature to import the old ones from here. Since this community is really strong, it survived the past data losses, but usually this means the end, especially when it happens more often and therefore I don't think it is worth to risk it.
On the other hand a more permanent solution would be nice as well, but as far as I remember we already payed for the vb license, right?
