This very site is for profit also and so is RCU but the atmosphere does seem a little different. I post here and at RCU knowing that a profit may come from my contributions but I do believe the owner of these forums understands the term president of a non-profit RC club and does not mistake it for a for-profit business as the RCC owner did.
The ads on these sites are less intrusive also and I even click on them from time to time. Perhaps I will do the same some day at RCC but not right now!
