Where can we share genealogical resources?

I have come across a number of valuable resources that I use in researching my 9000+ tree. I am happy to share but do not see a means of doing so. I’d love to see us compile our own database.
As a follow-on, I noted in the last newsletter that Mr Syffert has started indexing German families but at the time it was only A-F. I have lots of family in G-Z but was unable to email Mr. Syffert from the newsletter link. Hopefully he will respond here.
