This is such a great idea. I’m hosting my podcast on Squarespace, which cuts off the RSS feed at 100 episodes, and I’ve had a few people ask me if there’s an easy way to download older content (there isn’t). I’d love to figure out a way to bundle back-catalog eps together into something that patrons could download with one click.
Along those lines, one of my rewards is an MP3 of an audiobook, so whenever someone joins at that tier I just send them a message that has a link to a Dropbox folder. That might be a good way to handle older podcast episodes, too. It’s a little tedious to message each individual backer, but the Benefits manager makes it fairly easy to see who’s owed what.
