Well, extending the list is definitely my first choice, you keep the dynamic that way...but we'll see how it works out for a few days, meantime looking for the required widget....but that could be a possibility (Subforums for blocks treatments, another for ketamine and SCSs and suchlike...)

Yeah, it's an idea. I'll talk to Curious and Jo in a few days when we see how we're going. Forum may just flatly say no...but this is what I just *lurve* about this place - we have options and choices. We're so lucky to have fallen on out feet so very well.
Not just being "nice"...this is a great forum platform you have shaped up for us, DocJohn.
Very many thanks and ...
all the best!
