this really belongs in the noob forum, but i have too many posts to put this question there...
i've tried all the obvious things (aka. clicking around the member's info at the left of a post...diddling around with the "advanced search" facility...in that large pull down there's damn near everything EXCEPT spreadsheet)
...right now I do a garden variety google search for "XXX's spreadsheet" and it's hit or miss (mostly miss)...
i figured there's gotta be a simple way but the "knucklehead gene" is strong with this one
