Bennu3D and other libraries are very interesting, but people won't use them because they do not have documentation, let alone English documentation. I would suggest to the creators of these modules and possibly users of them, to document them first, before advertising them. I realise no one will do that, so maybe just adverstise...
Of course the Wiki is a great resource for most stuff and Booleansoup sometimes. The IRC Channel #bennu on irc.devhat.net can be added too.
This is a good initiative and vital for the survival of an English Bennu community.
