It doesn't tremendously matter, anyway, I don't think, although it admittedly would be kinda nice to be able to be able to tell who was in the forum you were browsing. Still, if you care that much, click "Currently Active Members" on the main page, and it will bring up of a list of all the active users who aren't in Invisible Mode and what they're doing at the moment. Nifty.
