Premise: Better utilize your army of players and the Lamannia server for your testing cycles.
- Create a more formal bug-reporting system (outside the clumsy forum-reporting) where players can test on Lamannia, report bugs, and receive bug-bounties if they find an bug previously unreported. Many software companies successfully utilize security testers to scrutinize their software and pay them bounties as incentive. In your case, your bounties don't have to affect your bottom-line—just offer virtual store items, points, etc. depending on the severity of each issue found.
Note: Make sure "replication steps" are a required data element by the reporter as this is huge amount of a software developer's time. With this onus placed on the reporter, it will allow your developers to quickly verify, etc.
- Once a bug is able to be replicated, it can be formalized, documented, key-worded, etc. so other players can see and search the existing bugs database to avoid duplicate reporting. Keep this ongoing list public and searchable. Yes, there will likely be hundreds, but isn't that the point?
- Allow your players to prioritize the known bugs by voting on those they think are most impactful/meaningful to them. Once you capture what your fans really want fixed, you can merge your internal priorities into your developer's to-do list.
I think such a system would be more beneficial than the existing, informal system. Use the existing account authentication database so players can't cheat the voting system. Decide on a simple system for the voting. Perhaps X votes per player per month?
I would go so far as to say that given internal specs for development of such a system, I bet a few of your fans could develop such a system with placeholders where you could plug in your own authentication and database calls where needed.
