A few months ago, at an AspirationTech conference in Oakland, CA (one the best conferences I've ever been to - by the way), I found out about UserVoice ... a website that provides "users" [of a product] a chance to voice their opinions about what features that'd like or bugs they want fixed.
So, if you're an OpenMRS user and you have an idea for a feature, click on the "Feedback" link on the left edge of your browser to submit an idea to OpenMRS. This is kind of an experiment at the moment, but I'm hoping we can solicit some good suggestions from our users and give you guys "a seat at the table" as we start planning out our road map for the upcoming (already in-progress) year.
There's also GetSatisfaction. I haven't used it yet, but have heard some good reviews. If you have comments about either or another feedback tool, please let us know.
