I figured out a workaround!
Make sure cookies are enabled for our forum. Cookies in dillo disabled by default.
Edit /home/you/.dillo/cookiesrc to look like this:
DEFAULT DENY
supergamer.org ACCEPT_SESSION
Then open dillo and attempt to login as usual.
It should fail as before.
Click your mouse in the address field so the flashing cursor is there. Hit Enter. It will act as a redirect and pass the final info to the server and log you in.
Enjoy

Thanks! Worked great. Back in dillo, sigh.
My forum session has never expired. Yes dillo is just great and fast, reading papers, searching in amazon you name it. If java or frames are needed I go as far as possible in dillo, then copy URL over to firefox or opera and continue from there.
