The quote below right off his site. Is he selling, sure. When you get a commission you are a salesman for those products wheather you actually work for the company or not. Do I have a problem with that, not so much. It is informational to the group but a line still has to be drawn in the sand somewhere.
Hi Dan,
While I understand the feeling, it's hard to draw a line, and it requires additional work for the moderators.
I also notice people offering used cameras, lenses, and what have you, with a frequency and quantities that suggest it's more than a garage sale. And few other posts are made by those individuals to benefit the LuLa community.
I don't really care, other than having to mark those posts as "Read" so they don't clutter the list of "Unread" posts.
The OP, on the other hand, does respond to questions and he offers examples and other information related to Plugins. He also takes questions back to the (in this case Topaz) Beta testing team and brings them under their attention. Sounds like a win-win to me. And who'd object to an additional discount, not me.
Cheers,
Bart
