Right now it doesn't look like it's really working how I might expect it. Just because I've come to the forums doesn't mean I've looked at everything. I logged on this morning and check a couple things. Came back an hour later and it gave me a handful of messages, even though I know there are a bunch I missed.
Seems like the email digest lets me not miss a thing, and a way to look at all messages posted over some time period does that but using last time I logged in ASSUMES that I looked at everything.
Anyway, I love the site, great work. I'm a believer. Way better than yahoo, quite frankly I'm shocked that they can't do better.
