Lately a couple of people have been asking about the formal process for creating an in-play guild, so I thought I'd weigh in on the subject.
Anyone is welcome to form an in-play group, be it a guild, noble house, business enterprise, or what have you. This is as simple as getting a few people to band together for a common purpose. Who those people are and what your group's goals will be are entirely up to the group. For example, the Brotherhood of the Bladed Gavel is a group of our oldest players who have banded together to enforce order and justice in Jastrey.
For the purposes of forming a group online, the only requirement is that you have at least three members, that you write up a good name and description, and that you designate the person who will administrate your membership online. Once you've got that covered, just submit the information to me and I'll set it up. This will give you a private forum to discuss group business amongst yourselves, and your group will be listed on the Groups page of the site for others to see and potentially join (with your approval, of course).
Note, for the brand new folks perusing the site, that there is no requirement to be part of a group a la Role Models. It's perfectly fine to play as an independent character. Whether you join a group or not is entirely up to you.
