I was thinking of maybe somehow having a drop box of some sort implemented where you can easily upload your excel, word, or whatever type of file your tradelist may be in. Users could then go see the latest uploaded files under "Tradelists or Collections" and easily browse users collections or tradelists. I just thought of this idea and it's early in the morning so work with me!
I feel as if it's a halfway decent thought and wondered if anyone else likes the idea as well. Thanks for looking!
