The development of VPLG is now happening at GitHub: https://github.com/dfsp-spirit/vplg
We will continue to use this website at Sourceforge for releases and other stuff though. So if you are not a developer, nothing changes for you at this time.
If you are a developer, you will notice that the repo here at SF is now read-only, and that you cannot commit to it anymore. Please contact Tim Schaefer to get access to the repo at GitHub in that case. Please tell me your GitHub username in the email.
