I have had a play at the new forums, and also was just able to navigate through Aimoo without any trouble, even though there is still plenty missing.
The more I play, the more I find free form easiest in general, and when I am using a dial up system, it is the quickest. When I use Broadband/DSL the others are quick and easy as well. I don't know if Aimoo will be corrected (figers crossed) but the new format is workable.
