Well I wrote up the following awhile back - changes I made which I believe helps out in the speed for me. You can find it here:

Computers (coan.net, 2007-03-12 20:16:01)

Plus it's not in the above, but I believe the nofont option is also a little quicker then the castle theme - but if you want to had additional fun, there are other external .css files you can try.

In setting, in the External style URL: area (plus make sure you check Activate external style right next to it), here are 3 that I've made (Just enter the http... address in the box on the settings page.):

http://coan.net/coannet.css - an "old" style look of BrainKing
http://coan.net/coannet2.css - same as above, with addition of "move" button near TOP!
http://coan.net/coannet3.css - same as above, with addition of dice poker dice choices near top (covers some of the screen, not pretty - but beats scrolling down for every roll)

Anyone is free to try those 3 out - and if you don't like it, just uncheck and use the any of Fencer's choices.
