Back in December, when an injunction was issued against OpenBTS, I had put in a request to SourceForge to purge the project. Then I removed the non-compliant material myself. Then I forgot about the purge request. Now SourceForge finally got around to purging the project.
For anyone who was on the OpenBTS mailing list at SourceForge, I apologize. I'm seeing what can be done about restoring the mailing list and web pages.
Until then, I'll try to find another place to host the web pages.
