OK, Lisa, here's my 'input':
1) I get the error message for "New since..." at all times of day, both when first entering the site and when trying to update when already on the site. And yes, it does not update properly, if at all. I don't even try to use "Today's..." or "Search..." because they haven't worked in such a long time.
2) I rarely use the 'Find' function but I have had some problems with it, too, but again, at all times, I think.
3) I've had problems at these times as well as any time of day. I haven't paid particular attention to the time or whether I could even get on the site or if it was just the error message on "new". But I did notice last night that I could not even get onto the site during this time but then when I tried again after the hour was up, I did get on.
I too have been trying to change my avatar without success (in case this is related to the other problems).
Basically, this whole situation has been very frustrating for me. With the sheer volume of posts lately, it's very difficult and time-consuming to have to go thru every group of threads to find the new ones and those that I'm interested in reading. I can't always use the thread title as a guideline as there's currently many threads that have gotten very off topic!

And I'm sure the problems are making it that much harder for the moderators to keep on top of things. If things aren't resolved soon, I'm afraid many people, myself included, will not be visiting very often.
