I believe the actual password is hashed client side and the hash is sent, but yes, in the clear.
But honestly, if you're using the same password here you're using on your "important" personal accounts (banking, etc), you have bigger problems to worry about.

I just sniffed and I can confirm there is some kind of client side hashing that goes on before it sends the password, and the hash value does not match the one for the cookie. Otherwise one could sniff that and just add their own cookie.
If your web browser has javascript enabled you will use an MD5 hash on your password before you submit it, otherwise your password is sent in clear text.
Having either one is enough to gain access to to this site.
