Two questions here. Is the Pridnestrovian Ruble not used enough to be added to Unicode, and did I mess up by sending my proposal thrice?

First off, is the Pridnestrovian Ruble not used enough to be added to 
Unicode? I mean, Pridnestrovie (Transnistria) is a relatively small and 
unknown country compared to the other currency symbols in Unicode. The 
state's not even recognised...

Also, I had to send the proposal for the Pridnestrovian Ruble 3 times. 
First email had a broken PDF and also had many broken caveats, and the 
second email managed to forget the date.

They haven't responded in two weeks. Patience may be key but something 
tells me that they aren't getting back. Did the triple email make them 
no longer respond? Maybe it was the double email, or maybe they're just 
drowning in emails?
