Every site depends on some key factors - an active owner, financial support, and people willing to spend time to keep it up to date.
Here at HW we are fortunate. I know of several other sites that have collapsed for lack of support, or simply because the owners gave up.
I would suggest you contact the site admins to see how you can help. That's how I got roped in here.
After I posted this, I did a little more searching, and found that the last co-founder of the site had passed away. I'm not sure who might be maintaining it now.
Howard Hansen (hrpca.org co-founder) has died
