Add disk space quota mannualy

Agreed. To be honest, we have clients who prefer doing most of this stuff manually. I think they're nuts but that's the way they want it.

Not built in. Considering many of these installs promote themselves as having unlimited bandwidth for endusers, there's not been much interest in something like that. Also since bandwidth is monitored by the box and not the wp software and there's hundreds of different types of box setups, that's not something that could be created easily. What would work for someone on a CentOS box probably wouldn;t work for me and my *BSD boxes.

Check your databases' charset. Probably on latin instead of utf8. If so, get back to us for some fun times.

if you try to change it from what it is into utf8, you may screw up something. There's a couple of threads on the mu forums (and I think a couple here) where we were pushing for forcing utf8 out of the box in core (and the plugins) but doing that messes other things up.

So what charset are the databases?

Well if you want to take a shot at it, you can convert the latin1 ones to utf8.

It;s not pretty. A very strong suggestion to back up your databases before hand. It's very easy to screw up something.

You should contact your host about setting the default to utf8 to prevent future created databases from being created as latin1. (I;m suggesting that since I don;t know your hosting environment.)
