[sudo-discuss] excel class

Hey hackers, sorry if this is a weird question or not appropriate for this listserv. Do any of you know of a good one-day intermediate excel class I can take around here? My work will pay for it but it has to have a somewhat legit-looking website and payment situation so I can send a receipt for reimbursement. It'd be cool to find some one in my community to support, but there's gotta be some institutional elements. The kind of thing I'm talking about is like http://www.academyx.com/training/san_francisco/excel/intermediate/ or http://www.pryor.com/mkt_info/seminars/desc/Y7.asp?EventCode=170028 Again, sorry if I'm way off base in asking this list. Just tryna get educated on my work's dime and send the proceeds to a rad community member... -- •amgo•
