problem ID 0156282 is not mate in one because the opponent can block the queen with a pawn making it mate in two can that be fixed?

I just added mate in 2 as a tag.  At least players can now vote for the correct solution.  I assume that eventually staff (or a computer program) will go through and delete bad choices.

It looks like the problem was correct but the tag was wrong; Nice thing about the public editing system is that now it's fixed without staff intervention.

It's not quite that simple.  Yes, premium members can add tags (as I did), but staff still has to remove the incorrect ones.  Actually I only got involved because it was a Saturday and I figured staff would be busy with more pressing issues.  They were right on it though, and the incorrect tag was gone within minutes.  Sorry about splitting hairs on this, but I thought you would like to know....
