Comment Lucky you (Score 1) 360
You are lucky enough to have users that actually report problems, rather than just complaining that "the new version is crap" at the coffee machine.
Setup a bug triage task, assign it to a different developer each day (because it's boring). Precisely mark the bugs that are not submitted with enough information.
Every Monday, Identify the top 5 users based on the number of bug reports they send, and the ratio of their bug reports that miss information. Set up a meeting with each one of these users.
Sit next to each one of your top 5 users, and write the mails describing the issues with them (mark the previous one as duplicate of the new issue). These users are willing to give you information, educate them on the information you need.
Then do it again the following Monday; your previous week's top 5 users shouldn't be in the top 5 again, since you wrote their bug reports with them.
Be transparent to your management on this new task you are setting up, and its cost. They may be willing to help you.
