No I did not. I searched but never came across that thread. It's apparently new in RM7. Works great. Many thanks!
This specific feature is new in RM7. But even before RM7 it was possible to export and import source templates. The way the old way works is that the export process turns the template into a file that is outside of RM. Then you can send the file to the other RM user, or put the file on a Web site from where the file can be downloaded, etc.. Having received the file, the other RM users does an import which takes the information from the file that is outside of RM and makes it into a template inside of RM. Or you can just do the same thing between two databases, both of which are on your own machine.
I used the singular "template" and "file" thought the discussion, but you can export several different templates as files, transmit the entire collection of files to the other RM users, and then the other RM user can import the the entire collection of files as templates.
With the old way, you have to export and then import templates one at a time, and the only thing that has to be transmitted between RM users is the file (or files) containing the templates. With the new way, you can get all the templates with one fell swoop, but you get them all (no choices possible) and both RM databases have to be on the same computer. If you end up importing more than you want with the new way, you can just delete the ones you don't need.
