Premade campaigns?

I've played D&D before, but I'm planning to start a campaign with my friends, and since I'm the most experienced player and the one putting it all together that makes me the DM by default.  Are there any premade campaigns that I can load into my Roll20 account for my players to play while I get experience DMing?

Short: No. There has been some talk about adding some to the marketplace (use the search to find them).

While there isn't any built into Roll20 itself, Wizards does have a premade campaign that I am actually currently going through myself. It definitely has helped me learn how to DM and really gets people into the mechanics of the game without having the stress of having to create your own universe to start out with. Name of it is Scales of War.&nbsp; <a href="http://www.wizards.com/dnd/archive.aspx?category=all&amp;subcategory=adventurepath" rel="nofollow">http://www.wizards.com/dnd/archive.aspx?category=all&amp;subcategory=adventurepath</a> &nbsp;You can find all of them here. The first three chapters are free to everyone but everything else you'll need a paid account on their website to access.

What edition of D&amp;D are you looking to learn? Knowing what system someone might be able to find something on the web that is free for you to look over. For older systems you can go to Dragonfoot.org to find a lot of free modules to look over and learn from.
