Thank you! My fingers were getting tired from forwarding the link.
The link has no advertisements. It was set up by a foster parent. Don't know the person, but what a great guy! They are looking for moderators for each region. He also has a poster you can print to advertise the site.
There isn't much on there yet, but hopefully the word will get out for all of us.
One tip: To post new items/requests find the state, click on that, and then click on the county below it (if there is one). Then you will get the button to add posts. (Learned that the long way).
Here's the link:
