I was also using the social network site tribe.net at the time and I really liked how it worked. Tribe has had its issues though and in particular it has become increasingly less reliable in the last year.
Supposedly, even if you quit the site and delete your account the new contract states that Facebook retains the rights to all content you had posted even if you decided to quit. Needless to say all of hell broke loose on the site.
Within a few days over 60,000 people joined the group ‘People Against the new Terms of Service’ threatening to quit Facebook en masse on March 1st if the TOU didn’t revert. Last night an announcement was made that the new TOU would be reverted to the old TOU.
I guess the People still do have some Power.
Join the group and keep it that way. Go here to join.
