How about a documentation wiki?
I have built up some knowledge with ABP now and don't mind sharing it. Some of the documentation has been brilliant, but some I struggled with.
I'm suggesting this not for existing ASP.NET devs with experience but people like me who are relatively new to the field and don't necessarily understand some of the stuff in the documentation.
I feel there's a real opportunity for ABP to be a great way for newbies like me to get up to speed and act as a gateway to further .NET-based development.
I'd be happy to contribute and help with such a Wiki.
