I have visited several sites around Greater Manchester area. Some are practically empty becase they have no editor, and some have had no posts since I left one about local meetups. Bolton has more activity than any in Gtr Manchester, but it's the opposite side of the area for me, unfortunately, although we did have our last meetup in Bolton, with GinnyTonic and two other editors from Chester and Blackpool.
Most days, I forget the local sites are there, unless an editor comes over to the main forum to say something about them, like JuneH from Llandudno. I guess the local sites need a bit more PR, or maybe 1-click links with posts from the main forum to a thread the editors woud like us to look at.
