Apologies if this has been posted before - I couldn't find a thread with it:
Can I/How can I rename a template created through the template builder?
Also, I noticed that it says in the help:
"Duplicate: Make a copy of this template, and give it a new name. Handy if you want to make a minor variation of an existing template."
(from here: http://help.campaignmonitor.com/topic.aspx?t=210)
But I don't get an option to rename it when duplicating - it automatically gets called "blah blah (copy)"
We did address this in an email to you, but I thought I'd post the answer here as well for the benefit of others. When you duplicate the template, you can then update it and when you click to Finish and Save it will prompt you to name the template.
