Not sure if you are aware of this, but there is a file in your DSDPlus folder that is called "aliases". It contains all of the RID's (including names of users) and TG's. Just make sure you hit escape when you exit DSDPlus so that newly captured ones are saved to the file.
Here's mine so far:

Question for you, I've never had such a file and there is not one in there now. Is there some special way of initiating it to be created?
I have used the "Esc" button as you said since I read this but no file still and I ran it for hours last night after seeing this.
Thanks
