There are really only two forums devoted to helminthic therapy:
This first forum is the most active. Created by Autoimmunetherapies (AIT), this is an open forum that requires membership to post but any one can view the contents. Mostly patients of AIT talking about their experience using hookworms for various autoimmune diseases. This forum is moderated by Jasper Lawrence and/or Marc Dellerba, the owners of AIT:

The second forum is for autism and use of trichuris suis ova (pig whipworm, or TSO). This is a closed forum requiring membership to view the posts. Mostly for children trying TSO for autism and other diseases. Stewart Johnson, the site creator is moderator. Hasn’t been very active lately:
