the server is public. all people need to do is register at the server forum, at least that what the process was when i last saw tank mention any thing about it. i have had a few people who watch my videos ask to join, I gave them the link to the server forum registry thread.
also we have something like 6 new people who play regularly on the default server.
Indeed, there is no privacy per say. But we aren't going around asking people to join. I don't want to advertise this server unless that is what this community wants to do. I've decided that I may do my own venture, taking what I've learned, but I'm not going to make the decision to just start bringing in random people. Everyone here should either be from these forums, or friends of members of these forums. Friends of friends may make the server more populated, and that would be great. I don't think random people would be so fun.
I'd just like to thank everyone who has been generous enough to keep the server running. If there is any feature y'all would like added, you need only ask and I'll do what I can to make it happen.
-TEKKIT UPDATE-Updated Tekkit server(Not 1.2 minecraft, but 2.1.1 Tekkit). This requires, at least for the next 4-12 hours, you to select a manual build in the Tekkit launcher. Read the news on http://www.technicpack.net/ for details. If you are getting errors about missing mods, this is the reason.
