As mentioned, a topic that comes up frequently.
This is a poll taken/discussion thread from 2013( I logged in for the first time as a poster that month) for reference:

and another thread started in 2011.

As for the other City locals mentioned in the OP they were created before I was even a member.
When it comes to Man./Sask, all decisions on the format would be made by Website Management and Administration.
Any way, it's open to discussion as a thread..
