Thanks TyWooOneTime and Helios52 for the tips and advice. All very helpful!!
I'm still a tiny bit foggy on the site's matchmaking trade capability. So, until I join a "Community", I will not see any sort of recommended trading partners via Deckbox, regardless of my wish/trade lists and local setting (local, worldwide, etc)? I have not joined any "Communities" yet via the "People" menu. Currently, I don't see any recommended trade partners in any of my submenus in my user profile page, no matter what cards I add to my trade and wish lists.
I assumed (perhaps incorrectly) that the site would match me up with people who only had local user accounts on Deckbox.org that needed cards that I am willing to trade, or cards that I need from them. So far, the only way I see to interact with other Deckbox users looking to trade is to inspect their profiles, one by one, via the "People" menu, then select their "Profile" page, and look at the bottom where it says "Trading Opportunities" (using Tradelist or Inventory). While this works, I know this must not be the proper way to do it because it would take forever inspecting user by user.
Which one of my Profile submenus will I see potential trading opportunities, once I have everything configured correctly and am a member of a community, etc?
Thanks so much again for the assistance!
