List of all elgg 1.7 plugin, mod, widget, theme...?

Hello,

I have seen lots of people asking questions that are subject to elgg 1.7 upgrade, migration etc. I think lot of cases the answer is simple, the mod/plugin is not for elgg1.7!  So, I want to request is it possible to make a list of all supported resources somewhere?

Another request is, can someone create a group only for elgg 1.7 discussion? 

Or, if there is something like that, can you kindly share the link here?

Thanks.
