I know this is not a big deal in the major scheme of things, but here in Israel we are 8 hours ahead of Chicago, so the maintanance time falls smack in the middle of our day. I can understand the need to do maintenance, and even though it is a bit of an annoyance to find the boards down, I understand that for the vast majority of people here this is the most convienient time.
However, one little thing that I think could be changed, is that the cookie that says when you last visited the site should not be updated when the site is down for maintenance. What happens is that I visit the boards, am told that it is down, come back 10-15 minutes later, and then find that all of the new posts have been grayed out.
Again, not a big deal, I know I can either try to remember not to go to the boards at that time or remember what time I was here for my new posts, but if it could be switched it would be nice.
