An idea would be to send our a general re-certification slip through the email they provided either in the survey or through WebEx's transcript feature.
Then I had a thought, what if I can use EXCEL to write the certifications with a macro that will personalize the certificate to the attendee's name and then send out an email provided. Cool right!
While a very clever powerusers, I'm not at the level. So I'm calling all EXCEL-gurus, what do you think?
