This thread has moved into territory very close to my heart, as I have a website for storing logbooks online.
I'm still a primitive fixed winger, so I don't know if rotary pilots use a different format - but I'd love to get some rotary pilots onboard and then tweak it to your needs.
You can choose to keep your logbook private if you like, and I'll supply a copy of your data for backup purposes any time you ask. From my logs I see that increasingly, people are liking to cross reference the data and see who has flown the same aircraft as them, or with the same instructor.
Because the system becomes more interesting/useful with more data in the system, I'm happy to accept your logentries in spreadsheets or other digital forms - I'll even type them in if you send me photocopies....
OK, plug mode off.
