Query from a friend of mine:
"We have a code released under GPL2, the source is available for download over the web and by subversion. However, we would like to have some better stats of who our users are and how many they are. Unfortunately, its impossible to track people downloading the code via subversion. Hence I had an idea to request subversion users to mail us to ask for the anonymous password - thus providing us with the number of users, and also with email addresses that we can use to send user surveys and other spam to. Would this go against the terms of the GPL?"
Opinions welcome*.
Thanks,
Malcolm
