Thanks Ondrej.
It would be nice to have some sort of advanced query operators to use so we could exclude words and phrases, or use some kind of boolean operators, i.e.:
("this phrase" | "or that phrase") + "and another phrase" !but_not_this_term
Beyond search, though, a really annoying thing is that there's no way (that I've found, at least) to find/manage MY content. I have no way of seeing a list of all Questions & Answers I've asked, answered, or contributed to, for example. And there's no way to turn off the notification emails as far as I can tell. Plus, I'd like to be able to get notification emails about things that I haven't actually participated in. Maybe I'm interested in the discussion but have nothing relevant to say at the moment.
This goes for "Articles", as well. I've posted comments on Articles and I have no idea how to tell if they've been responded to without actually revisiting the article periodically. That's assuming my comment has even been "approved" -- which I have no way of really knowing. I remember once I commented on an article asking a question, and I kept checking back and it seemed my comment never got approved (or at least I wasn't seeing it show up). Eventually I just stopped checking back. I forget which article it even was at this point. And I can't even just search for my name because I guess comments aren't being included in the content when I search articles.
