I want to organise a podcast with some friends, with a gradual release schedule. We're about 6 people who meet up personally, but we can't get productive enough in our meetups, so we decided to use online solutions for sharing our speech's sketches and similar things, all regarding the podcast.
Until today, the only thing we have seriously tried is Google's collaborative tools, but they seem to be really distracting, and way too complex for the kind of organisation we need, which is rather simple.
What software should I use to interact with all the colaborators, including occasional guests (having in mind that not all of them are tech-savvy)?
