Hi Marineboy -- thanks for your interest. We're glad you're part of the community!
Each member of staff has made contributions in their own way over the years. There is not much of a process -- I observed these contributions and based on my interactions with these individuals and the relationships we establsihed, I offered them volunteer staff positions to help maintain and grow the community.
At this time I'm not looking to increase staff any further -- I'm mostly focused on optimizing what we have in terms of content and community. As you can see with the formation of the new Cthulhu forum, the staff structure is in the process of a bit of change as we speak.
Regardless of whether you're part of staff, a supporter, or a community member, the most important thing is that you share our love and interest in cephalopods, and you're part of the larger team interested in helping us better learn from each other on the topic of cephs.
Thanks again for your interest! Looking forward to your future contributions!
