To add to BSwagger's comment, there are enough traders on this site who have their wantlists and or trade lists complete that the ease in trading with these individuals realy makes it less desirable to trade with someone who doesn't. Once you do get your collection on the site, you will see how easy building trades is and why trading with others who have their collection up to date are preferred.
Most of us have taken the time (and yes it does take time but well worth the effort) to enter our lists on here. I suggest you do the same; you won't miss out on anything and you will get many more trades by doing so.
