@jerrybanfield - thanks for this informative post - helps a newbie like me a lot. But I also have the feeling, that it is just a drop on a hot stone... I mean the big difference makes the content and I saw posts, well written, but they got just one or two cents and other posts have some photos á la sex sells and get 40-100 bucks. :-/ I mean this is a bit frustrating...

Upvoted and followed.
