There are a few requirements right now that you must make before we consider your inclusion in the guild.
1. You must be at least lvl 55 to be in the guild. This is not necessarily set in stone as we have made a few exceptions. As we are a raiding guild first and foremost, however, we can't have a lot of lowbies in the guild because they tend to beg a lot (help me lvl up, give me some gold, I'm getting ganked a lot come help, ect. ect.) and we need to focus more on raiding and less on taking care of things members could easily handle themselves.
2. You must present a basic knowledge of the game in order to be considered. Most of the times this is obvious which is why a lot of members were not actually interviewed. Sometimes it is not, however. Once I asked a lvl 70 player if he wanted to join a new raiding guild and he asked me "What's a raid?" These people will not be invited or even considered.
As of right now these are the only actual requirements to be considered and invited into the guild. There are, of course, more rules that you must follow once you become a member. You can see those rules in their respective posts.
