Like many of the others, I'm new to Pax. I actually saw Dailus's post about looking for a guild and Kyahlia's subsequent response. I decided to look into it and I'm glad I did. Pax is a large, multigame guild that somehow manages to seem fresh and fun.
Like some of the others who've posted, I think the application process is great. It's basically a breaking in and getting to know you period. From what I can tell, you get out what you put in it. Like I said, I'm having a blast with it.
As far as in-game goes, there are always guildmates online. They've all been super friendly and easy going. The banter in the guild channel is fun and lighthearted. And did I mention there are always guildmates online? Can't state that part enough.
Voice chat, good people, good times... I'm happy with my choice. And looking forward to the end of the application process and becoming a full member!
