Activities to make Elgg 1.7 multisite-ready

It's a nightmare to apply patches to elgg core, everything can explode for a small change in the new version.

I had a look at all che multisite hacks and added few ones. I will document all of them shortly in order to discuss them and submit relevant patches to trac. 

Our target should be to make Elgg 1.7 multisite-ready, or at least multisite-with-few-hacks.

There are different Multisite philosophies, Fabrice worked on user-created community, I need, instead, one single user base spanning over many sites, each one with its own homepage, theme, dashboard and installed plugins.

See you soon for more details, in the meantime, please post your thoughs here.
