nice! good to see ! & happy to see you posting again! 
A lot & even most sites put up a place to take donations, and I believe ya’ll should set up your site to take them as well. Just put it over to the side & tell people that’s it’s appreciated if they can help out, it’s as simple as that. ya might not get rich, but I bet a lot on UE & on the internet would be willing to help out. A lot of sites & major projects get their funding way.
Anyway, glad to see ya’ll are continuing to work on . I like the layout and comprehensive way you explain, show, and work thru the BPs.
And I think ya’ll should post to the Wiki as you go, then link back & forth from your site.
oh well, again, good to see post.
