HiI get quite a few emails from folk who are having trouble logging onto the forums..
Invariably, these being pro audio forums, the computer of choice is a Mac and the browser of choice... Safari that's bundled with the Mac.
My recommendation is to dump the sucky Safari browser and download the free Mozilla Firefox browser for Mac OS-X from...
http://www.mozilla.org/download.html
... and all your problems will fly away! It's a better browser than Safari and you'll have no problems logging on here or any other DCForum.
All you Windows guys should have no problem logging on but IE6 has more security holes than a colander and the new IE7 sucks in my humble opinion.
You too would have better browsing if you downloaded Firefox for Windows. They also do a browser for Linux.
I must add that I have no ties with Mozilla but the program is free and eliminates problems and security risks with either operating system so am happy to pass the advice on!
