No, you could never ask a stupid question!!! Actually, I've been reading up on lupus and am learning that A LOT of lupus suffers also have overlapping syndromes - including IBS and other digestive problems.
Right now I'm not sure about boards. I really love these boards and I feel that my IBS is probably separate from lupus, so I can use the continued support here. I'll probably end up doing both - depending on my energy levels. I might take a break for a while...
