YD was a fantastic resource for safety information, dive site reviews and help, trip reports, physiology and physics; this is not unexpected considering that it had been running for a number of years.
The TDF team have been asked whether material originally posted on YD can be posted here. The answer is yes, as long as it is only your work which is copied across.
This means that you cannot copy across:
1. Other's quotes in your posts.
2. Other's images in your posts.
3. Indeed any material which is not your own work.
We will no doubt get approached by VerticalScope about ownership of said material (as they now own the content but not the copyright, that is yours) so if you are able to provide a note in your copied material along the lines of "This is my own copyrighted content copied from a thread on Yorkshire Divers and is not other's work" we would be grateful. A pain I know, but when we get requests from VerticalScope, even a simple 'Go away' email, takes time to process and deal with.
