Hi Mike. Here is the Customer Support FAQ, which contains the email contact in various categories of questions: <a href="https://wiki.roll20.net/Customer_Support_FAQ" rel="nofollow">https://wiki.roll20.net/Customer_Support_FAQ</a> Here is the comparison of subscription levels, <a href="https://app.roll20.net/account/supporter" rel="nofollow">https://app.roll20.net/account/supporter</a> A good place to start is the Tutorial, <a href="https://app.roll20.net/editor/tutorial/" rel="nofollow">https://app.roll20.net/editor/tutorial/</a> On the Free account, you can upload graphics (up to a quota). You could upload a complete dungeon built in another program or that you found online or have in a book. You could upload just some Doors. There are some free graphics in Roll20, and also a search that pulls some free graphics from the web. So yes, the Roll20 Marketplace is available with lots of wonderful mapping products, graphics, and pre-made maps, but no you do not need to buy them here just to create your own dungeon map. You can create your own dungeon map with a combination of Drawing Tools, Fog of War (which blackens and hides the unvisited areas), upload graphics, and add Marketplace purchases if you choose.
