I am in the application process for the Pax community. It is a two week long process where the folks try and get to know you a little better. It is an interesting take on the guild recruiting process and while it does not require an exorbitant amount of your time, it will definitely require a bit of thought and a few minutes every couple of days to complete the process.
At first I looked at it as a barrier for entry, but now that I am almost done I can see it for what it is. It requires just enough effort that someone has to work a little to gain entry into the guild. This weeds out the random guild hopper and troll since it requires a few minutes of their time over an extended period. Additionally, it helps the Pax community AND yourself know that you are serious about joining the community. I know I had to stop at some point to question if this was what I really wanted to do. Not that the initiation was all that difficult or anything, but I knew if I wasn't sure about joining this community it would just be a waste of my time.
All in all, it was ultimately an enjoyable process and though I haven't done a whole lot with this group in game yet, I can say that the application process shouldn't scare anyone off.
