FWIW, I don't know why this thread seems slow, but that is not the general experience in user groups here. They are generally as lightning fast as the regular board. I would ask The Man Upstairs (eric) to ponder this if you like. This isn't RWOL and stuff actually gets looked at behind the scenes here.
Also, welcome. We already HAD a Marathon Training user group and a sub-3 thread in the main forum, but the more the merrier.
