I am trying to create a database of potential volunteers, including each date
we have made contact with them. There are a lot that have not replied to
emails for whatever reason so I want to follow-up with them. I just need to
know when to contact them again. There's got to be a way to use excel to
calculate the next date each person needs to be contacted again. For example,
2 weeks from their last contact date, so then I can just sort by date, and
see who should be e-mailed each day. I know it can be done but anything I
find wants me to pay for it.

I'm not sure if this is the best way to set this up or not but I want this
info in my database. So far I just have these columns (so I can sort each)

NEXT CONTACT, Initial, 2nd, 3rd, 4th, Last Name, First Name, Position,
Address, Phone, Email

What is the best way to set this up and what formulas should I use?
