We only use want to use 5 rating levels for members, not the full 10 which is the default, so we've set the "min number of posts" totals for levels 6-10 artificially high so that they're not used in practice. However, on members' profile pages the maximum rating level now displays as 5/10 which some members are not happy with (understandably). I don't see how we can fix this situation without implementing 10 levels? It would be good to be able to specify the number of active levels in the Settings -> Members tab so that the rating displayed on members' profile page uses the same for the maximum, e.g. 5/5 in this case.
Another solution would be to disable Member Activity from displaying on users' Profiles. More drastic but would actually work well for our needs - is there any way to do that?
I found a workaround for this using the second solution proposed above, i.e. to stop the Member Activity section from displaying underneath the Profile tab. Confusingly, to hide this section I needed to untick "Front - Can view member reputation" for all the usergroups I want to hide this section from. I say confusingly because although this section is titled Member Activity it's different from the content of the member's Activity tab. gVectors - maybe this section (i.e. the one with the reputation data plus other data) should be renamed something like Member Stats to avoid this confusion?
