Yes, Don. Some admin functions are not available, but basic moderation tools like closing threads, deleting posts, etc, seem to be available in Forum Runner. Also, posting using Forum Runner or Tapatalk should be immune to the "double post" bug that has affected admins/mods here.
Alf, I'm going to hold off on TouchBB support for now because I am having trouble finding enough information about it. I found some massive boards which use Forum Runner and Tapatalk, and that makes me feel more comfortable. Please try one of these alternatives and if you find them inferior to TouchBB, I'll take another look at it.
