I always look at it like this.
If i'm selling something and i just want rid,or not worried about how much cashola it makes,i dont set a reserve.
If i wont let something go unless i get either what it owes me,or what i think is a fair price enough for me to not miss it,i'll set a reserve.
On that basis.I dont mind people knowing what the reserve is.. if they ask i'll tell them. I dont see the point of keeping a reserve secret. But thats me. Its worked so far.
