I'm sorry to hear that OGL is causing such a server strain. I haven't
had much time to follow list traffic recently as I've been trying to
look for a new job while also revising for an engineering examination
on Monday, and my mother has just had a stroke which is currently
requiring the greater part of my attention.
A few days ago I made partial progress in sorting out an install of
the svn code for OGL. Hopefully I will be able to finish it on Tuesday
