We had the same issues at Roland-arranger.com. Site maintenance and dwindling participation made it too much of a faff to keep going.
We have to face it, there simply isn't much of an English speaking player base to continue some of these niche forums running and keeping up with forum software updates is a young man's game.
I am grateful to Kerry for keeping Nigel's dream alive despite the lack of traffic on this site...
