Users don't need to reply to get that information.
Just look at the profile of a user, and most of the time he/she will have filled in the version he/she is using most of the time (or multiple versions).
I *think* that 8.x versions are rather rare nowadays (and officially not supported anymore).
Most of the users will be on 9.4; however a good part of the user base (not the TM1 consultants) can be found on 9.1 and 9.0. 9.5 is brand new.
