I was expecting to find a "DTStudy" on this one, but a quick search says "No"
In searching I first tried "DT Study" which only got 3 hits.
I then tried just "DT" which got a lot more, including all the DTStudy threads & much more.

Could some kind mudelf do a quick search for "DT Study" (with the space), and consider retitling the three entries which vary from the standard format please?

Cheers
Nigel
