I've done my reserach...
It will cost $20 to get a raw dump of all this forum's posts, etc. I can then install a blank invision forum on the webspace and connect it to the raw dump of this forum.
Basically:
The forum would no longer be hosted by InvisionFree. The advantages I see:
1. We could set up the forum search function. No weird google search, something real.
2. No google ads (or if there are ads, the revenue goes into our pockets).
3. Basically unlimited upload limits. Our webspace is simply orders of magnitude larger than any forum could possibly grow into. Other limits would also be eliminated. Things like inbox space, etc.
4. I could set up a user blog. I believe anyone with a user name could set up their own blog. I haven't played with it yet, so I don't know exactly how it would work.
5. As a consequence of #3, image uploading could be more easily tied directly into how the forum is set up.
6. It would complete the transfer of all our resources into a single webspace.
Cons:
1. Attachments and uploads wouldn't be transfered over I don't think. Settings might need to be reset for all the users. This might mean things like avatars and signatures.
You'd also probably lose the text file download link for bots in the beastiary.
2. It costs $20 (it's not going to break the bank, but...)
3. Any posts made between when InvisionFree dumped the forum and when I could set up a new forum on the webspace would be here in the old forum and not in the new forum. Basically there could potentially be a day or two gap, perhaps even longer, in posts.
What do people think?
