OK, things are moving right along and stuff will probably be switched over in the next 1-2 weeks. We will be upgrading to YaBB 2.3.1 and will try to make it as painless as possible. Since DNS routes data/requests to the correct place (no matter if physical location changes) you won't have to learn/save a new URL. Suraklyn is toying with putting a "donate" button at the top of the page so folks can chip in a few bux if they feel the forum offers them any real or perceived value.
If we move directly to 2.3.1 there will be some work on y'alls parts. Here is a quote from YaBB:
"- In user profile, avatars, signatures and URL links have to be verified and re-Saved by ALL members."
I think if we upgrade from 2.1 to 2.3, import data, then upgrade to 2.3.1 we might not need to do anything. I don't know if the hoster will do that or not but we are checking and requesting.
I will probably either put this old forum into "Maintenance Mode" when we move data which will not allow anybody to log in or maybe I can take the write permissions off the data files so people could still log in and look around but not create/modify/post anything.
More to come...
