The software that runs the forum needs to be upgraded. Normally, I can do the upgrade with very little downtime. This time, however, I need to move everything to a new server, and I'm choosing to the do the upgrade while I do that. I need to put the forum into read-only mode for about a half a day or maybe a bit more.
When it comes back up, it will have a rather dramatically different theme; the stock theme that comes with the software. This is probably just a temporary thing for a few days, but, frankly, it's not very high on the priorities list. The new version of phpBB breaks something in the custom theme that I wrote for the older version. I've actually tried 2-3 times already to fix it with no luck, but now things are such that I'm forced to upgrade at the cost of loosing all my work
The new theme isn't great, but it's usable. I'll do my best to make it prettier and smooth the transition as much as possible.
Questions?
But it's important to me that it's done as the way I had hosting setup before ended up costing me way too much money ... 
The grid just has so much more room and, I believe, creates a better separation between the different forum purposes; cramming them all together into a table/list might be more efficient in some ways, but my eye finds that really unattractive and I don't find the grid to be any slower; there are actually more forums shown at one time on the grid that in the list.
