willy, i'm trully impressed - after reading your post about all pages now showing the page title, any slight doubt has been removed from my mind about boincstats being the best, you trully are dedicated to making a great site, and it shows
considering your comments about the difficulty (which i can sympathise with) this is a great achievement
just one remaining minor change to reach "title perfection", that would be to change the order of the items:
currently you have:
"site name" | "section" - "page title"
however, the order is important, for example when users have a lot of IE windows crammed on the taskbar they only get to see the first dozen or so characters (or when task switching with Alt+Tab).
Reversing the order helps greatly.
besides, most applications/search engines etc. crop the page title to about 60-80 characters anyway, and it's less important if the site name is cropped, than having the page name cropped, nevermind the fact that you want the most descriptive part first, and that's the page title (imagine a user looking down a list of links, especially if they're alphabetised), also it avoids having all your actual page titles starting with the same text
having the actual page title first, the category/section, then site name is the most helpful order for the user
trust me, this stuff really does make a difference, it's noticed most with e-comerce sites, a usable site will make more sales than an unusable one, usually quite a vast difference (we're talking 50% here, that's a lot of turn over), but as for boincstats, it makes the site easier to navigate and use, making your users happier
users may not notice it (it's a subtle thing after-all) but they appreciate it, users usually give up with an unusable site

maybe when you have time you could address some of the other issues raised in this thread, while i'm posting, another one for you (i think that's 4 now :p), on the
main BAM! "welcome" page, there are a lot of "click here" links
if you want/need suggestions for replacements, just yell
