This thread is manly focused on the people who are starting on new servers and go into global saying "Hi, i'm new, are there any new groups?". Usually players like that tend not to go on the forums and check out things, but just in case you are here read on.
I am writing this because over the past days I noticed players doing this: they join the server, check for groups and get no respond then leave the server because no one wanted to play with them.
I have been there and I know it is hard to find a group, that's why I wanted to point you towards the private server section, in there you can find some threads about different servers, both PvP and just PvE. Before you join a server, go over there and check the servers out. Often the server admins have created a site revolving around the server, even have a teamspeak server going.
Please take this advice, this game is not for single players so go check out the private server sections or guild section for new servers, don't just pick a random one. Not every size fits all.
