Calling it the DISCUSSION site will avoid some confusion since I've been calling it a FORUM up to this point.
The structure is such that the site might be call PROTONPALS DISCUSSION
Under this discussion site, there are CATEGORIES and starting with HORMONE FOR THE TOP CATEGORY AND FORUMS,
and below a FORUM in the tree structure are multiple TOPIC and DISCUSSIONS
The main topic of discussion will be HORMONE THERAPY and under hormone therapy will be multiple FORUMS.
Or main topic of this discussion site could be SIDE EFFECTS with HORMONE THERAPY being one of the FORUMS then several topics under that FORUM.
