I created an in-game bug reporter for Industries of Titan. Users can type in a message and it gets sent, along with a screenshot and a zip of their latest save to a server for us to look through.
This is an example of how to set up something similar in C++.
Update: @sswires89 pointed out that this relies on MimeHttpUpload.h
which is currently only available through
UDN. Sorry about the confusion!
