The normal way of making an MDG Technology available to multiple users is to place it on a network drive and tell the users to set up their EA installation accordingly. The GUI function to do this is in Settings -- MDG Technologies -- Advanced -- Add. This makes the technologies stored in that location available to the user regardless of which projects they open.
The registry key option is simply a way of distributing the setting without having the users do it themselves. This makes sense if you are repackaging EA for distribution on your internal network, because it eliminates a configuration step for the users. (You would then also include the location of your shared license key store, and any other options you want set differently from the EA defaults.)
It makes no sense if you're not repackaging EA, because importing a registry key is no simpler than clicking through the GUI and, to a non-savvy user, feels a lot more like strange magic where they don't understand what they're doing.
However, there is another way. This is essentially obsolete and you shouldn't use it, but it's still there and will probably never go away. From the help file:
"A method of importing MDG Technologies into the Resources window is available (right-click on the MDG Technologies folder and select the Import Technology context menu option) but this method is Not Recommended.
If you use this method, the MDG Technology is available only in the model [read: project] it was imported into, and the Toolbox pages, Learning Center, Project Browser icons and model templates are not available."
So if your MDG Technology is a simple one which only contains stereotypes, tagged values, toolboxes and diagrams, you'll be OK. This sounds like what you say you want, although I'm pretty sure that what you actually want is to do it right and use network storage instead.
If you're absolutely sure what you're doing and of all the implications, the setting is in the Project Resources window, in the Project menu. If not, go with the network storage option.
(There is yet another way, which is to package the MDG Technology for local installation into the EA folder in Program Files. This is better for situations where people are often off-network and working in individual projects from which they then export stuff to be imported into a central repository.)
