I just logged onto Google Spreadsheets, and I saw a "discuss" tab I hadn't noticed before. Has this always been there? I use Docs (I still mourn the name Writely) much more than spreadsheets so I could have missed this before. If not, it seems Google is pumping out yet more cross-integration with their chat service. I can only assume (and hope) that this will be coming out for Docs soon.

<< Has this always been there? >>
yes :)

On Docs (Writely) for me on the Spell checking Google isn't in the Dictionary by default and I've just had to add it. Why Didn't Google add them selves to thier dictionary?
FYI, the "corrections" I was given where, Go Ogle, Goggle and Googly

Google isn't misspelled in my Docs.
