How do you submit files for download on this site? I've got a bunch of charts that I think players and DM's alike might find useful, but don't know where to put them.
Well if you'd just like to share them in general you could attach it to a post in the appropriate forum, if you want something more permament that's a little different (and someting I'm not sure of).
Either way this would be better asked over in Meta, where a mod is sure to move it soon.
