Apparently, the plural of forum, when related to t’interweb is ‘forums’ not ‘fora’
There is an excellent reason for this, what I saw on the tele, but I’m buggered if I can remember what it is. Something to do with ‘forum’ having two, distict meanings in latin, one of which was pluralised to fora and one of which wasn’t. Or something. Anyway, I have written it on the internet now so it has become true.
