So here is the South Pool OPS's Research Toolbox. It is definitely a work-in-progress as I find more sites to put in here.
South Pool on GenUKI
GENUKI defines itself as a 'virtual reference library' and covers all areas of the country, from cities and counties to villages and hamlets. It includes transcriptions as well as links, and should be the first stop for the serious genealogist.
South Pool Online Parish Clerk (OPC)
Covers the area of South Devon between Dartmoor and the River Erme. "A collection of transcriptions of church registers and the 1841 census, plus a free lookup service in registers and other materials that have not been transcribed, for the South Hams area of Devon, England." (our4bears.net, accessed April 2015)
FamilySearch South Pool wiki
Adopted by OPC and OPS Ros Haywood, this FamilySearch wiki page provides info on South Pool and is another public Research Toolbox, with useful links.
FreeCEN, REG, BMD (FreeUKGEN)
A volunteer project, this " is an initiative to help make more high quality primary (or near-primary) records of relevance to UK genealogy conveniently available online, preferably for free, in a coherent, easy to access and search, facility or set of facilities."
A site chock-full of information about Devon: military, industrial, genealogical, educational, and architectural.
Devon Family History Society
Formed in 1976, this is the largest Family History Society in the UK. The DFHS states that its objectives are "to promote the study of genealogy and history, especially of Devon families and places, to educate the public therein through advice and instruction, and, for the public benefit, to encourage the preservation and transcription of relevant documents and records, especially for the county of Devon."
