The PC genealogy database software, RootsMagic can include preparer information on almost all the reports, charts, and lists it can generate. This information can be set once then included by selecting an option check box. In many cases the inclusion of preparer information is a default, so it will just work after storing the preparer information.
Please open your copy of RootsMagic and follow along with this video as I take you step-by-step through the process of adding the information then show you which reports, charts, and lists support its inclusion.
The process is very different in RootsMagic 7. You might consider updating for the newest process.
