So the solution that we (I) will find now, but not be the best, and mostly likely parts of it (perhaps all), will be temporary (albeit at least some, setup so that we can live with it for quite some time while we look for other and better solutions.
The solution sound good enough for now.
Mail: Getting a lyx.org address as a lyx developer has been a bonus, the mail account has never been intended for storing mail, and basically a forward has been required. So I am moving forward with moving handling of mail to google, and let them run the mail for lyx.org. (I already do this with gullik.org, and am quite satisfied with that.)
Just a question: do they do forwarding too? JMarc
