Review for Mail Merge by aparente001
Rated 4 out of 5 stars
Someone asked for clearer instructions. I found some nice ones at http://www.eecs.berkeley.edu/Staff/Procedures/tbird-mailmerge.shtml.
The one thing I haven't understood is how to edit one of the messages by hand after executing the merge but before sending.
