Bad Login?
 

I can't seem to get into the MC server, says I have a bad login.

White list might not be working or the server might be outdated. Or maybe both are just fine and you're not on the white list for some unknown reason. If the latter is the case, I'd ask Cat or Shade about that (tip: Ask Shade first, Cat's usually busy).

The Bad Login errors were on Mojang's side. A tweet from Tobias Mollstam [the lead web designer at Mojang] confirmed it. They are working on the problem even now, trying to nick the issue in the bud.

With the rate at which Mojang is churning out updates, I wouldn't expect the server to get updated anytime soon. 1.4.6 is just around the corner, with 1.5 expected to come out a month or two later. I doubt craftbukkit will be able to keep up. Heck, their last recommended build was for 1.3.2. Even if it weren't for the little snafu with the logins, I would wager the server is out of date and you wouldn't be able to get on, anyway.
