Mark, it's taken me two days to be able to log back in after having registered on the first day of the new Board. I chose "always stay logged-in" or whatever it's called when I first logged in, and, indeed for the first three days, the Board "knew" me when I returned. Then, for some reason starting on Thursday, I was back to "Guest" and I could not log back in. I tried both my original password and the one I chose to replace it, with no luck (I toyed with upper and lower case, just in case--no pun intended--the password and log-in name were case sensitive, but no luck). Finally today on about my fifth or sixth try, it finally "took" and I was logged in again. Do the cookies expire after three days if you don't post?
I also have one suggestion--could you maybe add the dates to the titles of the posts on the post index. It's easy to figure out now, but once we get a few weeks up there, it's going to be hard to remember which notes went with which days.
