I have moved mailing list of the Boost.Geometry library from server at OSGeo to Boost mailing list server. All existing subscribers and archives have been moved to the new server.
The new list is available at geometry at lists dot boost dot org. It is also mirrored at Nabble as Boost.Geometry.
The old ggl at lists dot osgeo dot org will be wiped out soon.
If anyone experiences any problems with the new geometry at lists.boost.org, please contact me directly.
Big thanks to the OSGeo Foundation for hosting the ggl mailing list and thanks to Boost admins for help with the new server.
