Subject Re: [DISCUSS] Eagle incubator proposal
Date Tue, 20 Oct 2015 18:58:57 GMT
I should also have some improved bandwidth both now that Kylin is nearing graduation and for
other reasons. I’ve been bogged down recently, but that’s starting to change.

If more mentors are desired, I’d be willing to help in that respect.
