I would concur with the many who lament the inability to check new comments in the gallery; this is a significant drawback, so it is pleasing to hear you hope to resolve it. In the meantime, a partial solution is to utilise the "recent activity" tab (if that is the right term). This provides a list of all comments and posts (but can get clogged up if someone has posted hundreds of photos from their latest visit somewhere....).
Thanks sooty - I hadn't found that option yet - that's much better!
I'm probably just being stupid and missing something really obvious, but where's this?
