What a coincidence!!!
I am planning on the same and will appreciate all the feed back.
I was part of Polygon in its infancy and had lot of trouble
navigating, as well there were groups who would not let you enter.
This is what I feel, to sell colorstones on Poly (based on my
experience then) you have to be quickly part of some group on
polygon. I am sure things must have changed a lot since then.
Don't you feel the monthly fee to be steep?
Thank in advance to all
