The only way we can constantly improve on ViPEC is when people actually use ViPEC on a regular basis as well as taking the effort to give us feedback on any new bugs, feature requests etc.
We are now making use of SourceForge's excellent Bug Tracking system. If you find any bugs, have any compile problems or even feature requests please submit them here. The developers will receive an email off all submitions.
If you have registered with SourceForge you will receive an email the moment the bug report is updated, on the other hand you can just surf back here from time to time to check the status.
