I have announced (even tweeted) a call for submissions for the next VMS/L&T SIG Collection. That's right. It's a collection now, not a tape. The last release was all the way back in Spring (for those in the Northern Hemisphere) 2007. A lot has happened since then. The collection has a new maintainer (me) and the historical archives have moved to the new DECUSLIBrary.COMpendium.
The current plan is to have all submissions in by January 1st, 2010 with the "VMS/L&T SIG Collection 2009 H2" distribution ready for shipping by February 1st, 2010. I do intend to have the collections released half-yearly. Hopefully this release will make up for all those that have been missed.
If you are interested in contributing, please head on over to the SIG Collection page and make a submission. You don't even have to be the author. If you see something useful drop me a line and I'll chase up the author and handle the packaging requirements.
If you don't have any software to give and you still want to contribute, then maybe consider becoming a distribution point. The physical media is distributed by tree. So, the maintainer sends out a bunch of masters which are then copied and distributed to local (or at least semi-local) recipients. Although, in this day and age of broadband internet I imagine there won't be too many people looking for physical media.
To give you an idea of what to expect in the 2009 H2 release, the following packages have already been fetched for inclusion.
