Hi @obani. Everybody loves free, so hell yeah bring some of those servers online. I do however, have a few questions. I'm a official dedicated server host, that offers dedicated servers on the fly, around the USA, & 3 country's. What are the specs of your servers? What are your uplink speeds & restrictions? Where are they located? With these servers being free, do you offer any kind of access remotely to the server (SSH, VPN, REMOTE DESKTOP, ETC..)
Those mods you're interested in bringing back, you'll have to sit down and sort through the code, those two mods are two of the buggiest. I did however have success with the xserverx bots but extremely buggy and a few things didn't work as they should like menus.
I'm sure there might be someone who can assist you with this, but as of right now I can't think of anyone who can put down what they're doing to help bring back those servers in working condition. If I got some time, I may be able to assist. Great idea buddy, and look forward to seeing these servers online.
