Upload & Sell: Off
The watchlist option is a perk for paying members. Making the perk available to everyone like you're asking, would be doing a disservice to those who have already paid.....
I don't think so, The watch list might make this a better place to sell and so will attract more sellers. When gear sells here faster than on other sites the sellers will all be here, not there.
So, it could go either way, time will tell.
