By 'topic' do you mean dedicated forum?
If so, there is a site suggestion forum in which you can discuss such things. Until such time as an MT forum is added (or indeed, if there never is one), then any aspect of MT you want to discuss can be posted here in general forum, or the 'competition fighting' forum, or I am sure even the BJJ/MMA forum wouldnt mind a Q. or two, as MT seems to be a popular component of many MMA practitioners.
Wildbill and Taison are experienced MT students (amongst others) and am sure will be happy to talk and be of help on the subject.
