As has been mentioned before, I think that using the new FindMyPast is just like using any new subscription site. I've had to take a long hard think about how things need to be done now step by step and forget about the old FindMyPast which has gone forever.
I've had a few tries of approaching it like that, having read from one or two people that they'd been able to find stuff that they couldn't before, and to be honest it is still proving a nightmare.
I had search results which stuck on page 76 (which I wrote about on here), the same page kept reloading, so in effect it wasn't giving results beyond surnames beginning with T - I reported this and apparently it has been passed to the 'tech dept'.
I always use the form for the records I want to find (not the one form for everything), but find that on the census forms entering a county is ignored, the drop down menus for birthplaces etc are impossible to fathom out.
If I enter anything more than a name and dob it is a problem.
(I've also found that names that were there before, now come up as a blank followed by the surname.)
If as a new subscriber I tried the site on a trial, and for example found that the search ignored any county or town I entered, then I wouldn't be subscribing afterwards. I would expect it to be better.
