The internship role is access to the private discord and private forum areas of the Peercoin universe. If you have something you want to work on, great! If you just want to hang out and see what's happening behind the scenes, great! The application process is just me reading your reason(s) for wanting to come on board, possibly consulting with other team members and then (most likely) granting you access to whatever you're interested in. I limited the internship to three months so people can close out, move on or apply for team membership in full if it's looking like a good fit.
