If a world is filled public, then the commish clicks private once the season starts, are the private world rules enforceable for that season?  For example; MWR?

I don't think WifS will enforce private world rules if the world filled while public.   Nor should they.   

No.
It is complete BS to even attempt to do so.

Thanks guys

Well, it obviously King Felix and I'd be unhappy about a 31 win team.    And a team that wins 54 with a 42m payroll and 41m prospect.   Both of them have been there more than one publicly filled season.   But I still don't think you get WifS to enforce booting those guys(maybe the 31 win team).

And if you go back through the chat it appears to me like they DID NOT go public.

They got down to one, and then someone suggested it, but there were a quick 3 or 4 objections/warnings about going public and how you couldn't enforce PWR if you went public, and then they were full.

All happened over 1 or 2 days, so I'd be surprised if they actually went public.

If that's the case, boot their *****.    At the end of the day, cebola is trying to "clean up" the world.  No one should oppose that.

We did not go public, I was mistaken... We had two commissioner changes in one season, so I think the 31 win team kind of slipped through the cracks of being replaced when abandoned... I actually agree with MikeT (horrible to say, I know) that no one should oppose cleaning up the world.  I think we finally have the right guy to fix things in Cebola, fingers crossed we can fill and avoid a merger.

A broken clock will be right twice in one day.  So agreeing with Mike is being half as accurate as that.
