I don't really know how well Scriptcraft was in the past before it was taken down. However, the guy Gummy is helping develop a TBC server that should hopefully be out this summer.. June, July -ish?
PlayTBC seems like a complete flop, but this guy has videos on YouTube describing how it's been in a closed development and he's coded things differently and all for the better..
I highly you suggest you guys check it out - his latest YouTube video below
