Hi Michael! Welcome to Roll20. The link Eric posted is a good place to start (hurrah for our Mods!). I would also suggest checking out the help docs section for more information on how to use Roll20: <a href="http://help.roll20.net/" rel="nofollow">http://help.roll20.net/</a> There's nothing to download, so it's all viewed in your browser. If you click on the "Virtual Tabletop" link at the very top of the site (next to the pinkish D20), it will list the campaigns you've been in most recently. Campaigns are pretty much how you use Roll20. You can make one for yourself or you can join one that someone else created. To join one, the GM needs to send you an invitation or a link. To create your own, just click the "create campaign" button on the "Virtual Tabletop" page. I highly recommend viewing the "GM Overview" video that Eric linked to first, though. It should clear up a lot of things. Also check out the player overview ( <a href="http://help.roll20.net/player-overview/" rel="nofollow">http://help.roll20.net/player-overview/</a> ) video to see how things work form the other side of the screen. The help docs section is full of useful information about basic (and advanced) Roll20 use. If you still have questions, feel free to come back to the forums! Everyone here has been super nice and quite polite in my experience, so don't be afraid to ask questions. Welcome to the community. :)
