I'm withholding judgement for now.
I too live on my email so I tend to see everything that comes in and and
sort it efficiently. Also can easily save off things I might need in
the future. On the other hand, the new site has a lot of advantages
and is much cleaner/neater.
I do see, though, that there appears to be a lot on the website that is
not showing up on the LML. I had had the impression that the two forms
were going to run in parallel. ...but now that I think about it, it
would be a hard thing to pull off technically. It would be good with
Marv or Paul would say explicitly how the two methods interact.
