My trick for getting on tribe easier is to bypass the home page. I have the tribal fest tribe and a few others bookmarked. I can usually go straight to a tribe I want to when I can't get in to the home page. It seems to be a regional thing too. I remember a time when I logged in from other cities. You can also just pretend you are in a different less tribe-populated city and have better luck getting in. Best way consistently is to go straight to the tribes I want to visit, which means knowing the tribe handle. For example, I go to bsbd.tribe.net to get here or tribes.tribe.net/fusionfestboiseid to get to the Fusion Fest Boise tribe, tribes.tribe.net/djamar to get to mine, etc.

Lately though since i've been using my phone to get online for the most part, fb is easier to get to, since they have a mobile version. I wish tribe had a mobile version. Hopefully they will.
