Tim:
You could probably consolidate your gmail accounts (if you wanted to), or at least pull mail from one to the other (again if you wanted to).
c. marlow:
using Gmail's fetch setting under webmail settings?
Sounds right. I haven't explored their interface for ages, to see where they hid everything.
That's another bugbear with webmail interfaces; they keep redesigning things on you, then you have to go hunting for something you need. Sure, mail clients do that, too, but far less often (in my experience), and usually their interfaces seem more logically organised.
