The IDL Usenet newsgroup has moved to a [Google Group]:
> This Google Group is a continuation of the Usenet group `comp.lang.idl-pvwave`, but allows for better spam filtering. It is for discussion of the Interactive Data Language ([IDL]), developed by Harris Geospatial Corporation. Questions about ENVI, a geospatial analytics software written in IDL are welcome. Discussion of the similar [PV-WAVE] language is also allowed.
The big question now is how to save the posts from the old newsgroup.
