If it's the same group that banned me, they won't want you to talk about a different group or invite people to join it, so be very careful about how you do it. Like inviting people by PM not by posting on the public forum. They're paranoid about competition from other groups. One of the reasons they were mad about me posting helpful links was because some of the articles were on a website that also had a forum. The articles were separate from the forum, but they didn't want their members visiting websites where they might find out about the existence of another forum.
It was this group here:
