This server doens't need anymore GM's as said before. If it needs any help, then it's from developers, people that know how to work with codes and are trustworthy to work with the server database, fixing bugs and imptoving server likewise.
Besides, it's not like you need GM powers to answer people questions (tickets), u can do it without any powers, just get in that chat and offer people some help, providing your knowledge, as chats are usually full with different questions.
