Hi Moondance,
You are a sweet trader, but there are many DPF members that take advantage of newbies and also offer very lobsided trades in their favor. So you really cannot trust a trader just because they are a member here. There are many posts that will state that fact on this forum.
Every morning, I get questions from friends asking me if they think a trade is fair. I will do the same in asking them. I think that is the safest way to go when you are not sure.
All of us have been taken at one time or another, and some of us many times. The sharks are here too, but conceal themselves well.
