1. The latest released files contain a working Thief and some addons.
None of the publicly available files are complete tho. You have to buy them in order for a smooth setup & gameplay, else you will be forced to work more for nothing.
2.there are dozen of threads about old serverfiles. pick them all, try out what works and what won't.. There's a huge amount of addons and poop, you just have to try them out yourself...
3.there is one, advertised everywhere here in this section, just check the header-ad out
If you have the will to work and you stick to it you can do much..just don't rely on others and use the search function because 99% of the questions which you will have, have already been answered.
