Hello. We are using the non-profit starter pack, and would like to send each donor (aka Contact) an email listing all of their donations (Opportunities) so far this year. I was told that I'd need to create a Visual Force email template to do this. I'm new to VF, but I do have experience with other programming languages, so just need some help getting started. 

Can someone please point me to an example of how to include a list of donations (aka Opportunities) as a merge field in the body of a mass email? 

Thanks in advance,
 

David
