So Either Google Reads My Blog
Or I have a decent amount of luck/good timing...
It's most definitely a beta...some functions don't exist and "Import from .xls" gives you an occassional dumb look. At this point, I could only import from a .csv which means formats and formulas go buh-bye.
And yes, I went ahead and loaded my super-secret "ssh, don't tell anyone" budget spreadsheet which is much less dangerous since I've renamed/removed anything that wouldn't be considered innocouous.
And Lynne, no invites yet, but you are the first on the list!!!!
