are you kidding me
i think it was taken down because there was a lot of failed add-ons in it
You can ask new people and they would not even know what RTB 3 is.
If he's new he didn't have any means to know what RTB 2 is, he wasn't part of the community during that time, and at this point RTB 2 does not matter at all; until now.
I must admit that having a RTB 2 repository archive at this time would also be great. But I am pretty sure lots of add-ons that shouldn't be there are there and in addition to that, it's so old that I doubt anyone has a archive of it, unless, given what Zacks said, dasord123 would cooperate with someone to set up a archive if he can't do it on his own.
