There is an excellent public discussion thread at http://www.geni.com/discussions/80238 where Geni members have been adding genealogical resources they have found since the thread was started in August 2010.
That discussion thread "internet resources" now runs to 13 pages, and it can be difficult to find relevant resources in that discussion.
Cross-posting of relevant resources in discussion threads in this project is welcomed, as is cross-posting in other relevant projects.
There has been some discussions of trying to collate and organise these resources in a project or Wiki page(s).
For some references to those discussions see http://www.geni.com/discussions/105001?msg=769778 and http://www.geni.com/discussions/80238?msg=769378 and posts following both of those.
