Long time fan of Morrowind, I've been following your project for years wishing I could help but knowing I didn't know enough to really add anything to your team. With your application for QA testers I'm excited I can actually contribute some. I have done professional QA for a year at a software development company. More recently I have done beta testing (public) for games like Prison Architect, and in-house (private) testing for RimWorld since it's initial alpha. I've used bug-tracking tools, my most experience is with Mantis.
My schedule is chaotic but I think I can dedicate probably 10-20 hours of beta testing every 2 weeks. Application attached.
