Short: I am looking for a very simple (configuration/maintenance wise) solution, that would allow to collect user-feedback/bug-reports from my apps/web-sites over the internet.
Long:
Right now I have very simple web-app written using ASP.NET MVC that receives http-post requests at http://localhost/feedback and saves them as c:\temp\{guid}-feedback.txt. I used UltiDev HttpVpn (BTW it's very cool) to expose this page to the internet without having to put my app in DMZ. I collect following information (through a feedback form in the app, or a web-site's feedback page): user name, e-mail, type of the message (feature request, bug report, comment), application name (hard-coded in the app that sends the feedback), and message-text/comment.
About E-mail:
E-mail is not good enough, since there will be no e-mail client on most of the computers my apps are running at (also, it takes too many clicks to send an e-mail).
About JIRA: IMHO JIRA is too heavy for what I need. I might be wrong, since I have never installed/configured it myself. Does it have a http-post interface (so I can put my own interface on)?
.NET on Windows solution preferred
FREE is a requirement
