Is Canning Town not classed as London
Was it not part of West Ham ie. Essex back then?

Yes, Essex.
I eagerly went looking for my Londoners and could hardly find any of them - but I know from marriage and death certs in the 19teens and 1920s that quite a lot of them had moved a little (and it's really only a little!) eastwards to become Essex Girls. I presume my shoemaker ancestor was busy making the white high heeled shoes for them all.

(Apologies to all Essex girls - including my mother - for the stereotyping!)
What I really miss (and have said to them, among numerous other suggestions and comments) about the 1911 site is that you can't connect family groups to check you've got the right Fred Bloggs age 47. (I also suggested that it would be nice if they could put place of birth on the results listing, as you can include it as a criterion in your search anyway). There's no fuzzy or soundexed searching on names at the moment (but I suspect that might come).
I've no idea how many people they've invited into the beta test, but I've been impressed by the speed, and the quality of the imaging is superb. At the moment, you can only download the images, not view them on-screen (to reduce load on their servers I think). Which is quite good, as it means I can't forget to save them.
You can also download to a spreadsheet all the records you've paid to see, which I think is probably going to be rather useful. Not sure how, but it does like a really good idea!
But I have already found a couple of transcription errors! The reporting system for transcription errors looks very easy to use.
