I have created email templates for our office to use but have encountered a small problem that I can not seem to figure out.

The template has our logo at the top, then the body of the message, and then a variety of information at the bottom. Each employee saves the template themselves with their own signature added to the message. The problem is the automatic signature. Our IT department will not allow the registry to be modified to solve this problem so I need to find an alternate solution. I tried creating the template using headers and footers but that does not work out well either. Is there no way to create a form and specify where the auto signature should appear??
