I did follow up with you via e-mail - I would like very much to collaborate on the spreadsheet! 
I am fairly proficient with Excel, so I’ll be excited to see if I can contribute!
By the way, even though you don’t use that e-mail account frequently, it would be a good idea to edit your post and remove the e-mail address at this time - you have been so helpful and friendly, I would hate to find you in hot water with our moderators, and I thought I remembered reading that sharing of personal information here was a no no.
