I just received a trade today. We both came to an agreement to ship on the same date. Both him and I had plenty of positive feedback on Fauna Classifieds so there was no real worry. If someone offered to trade with me and had little to no feedback, I would pass. In some cases where one person has a lot of feedback and the other does not. The person with no feedback will ship out first, only upon arrival and inspection of the package by the person with a lot of feedback will he/she ship out.
