The old forum was just getting way too much spam, and I was seeing inappropriate material. Too risky when young eyes are on the site. I take security and safety very seriously, so I've moved it all to Google Groups.
This is the first step in a series of upgrades to Zefty I will be making in the next few months.
So, if you had any open questions/comments about Zefty in the old forum, please feel free to post here -- I receive an email any time a new post is made, and hopefully this is more secure than what I had before.
