Pleased for them. I went to Edgeley Park a few times when I was at a loose end on a Friday night, years ago mind, actually saw them play Everton in the Cup, it was packed to the rafters.
In general it's good for Manchester to have as many clubs in the Football League as possible. And given that we've lost Bury (and Oldham, I think?), it's no bad thing that one's going up. Used to be a time when Manchester had more clubs in the League than any other city outside of London. And it's still the case that Lancashire has an astonishing number of clubs.
