I've never heard of this either, but it is my opinion that if your application is not accepted by nationals, then you are not recognized by nationals and not a member. Even though, you went through the process, I would consider this an "underground" line. Although I am not sure what organization you pledged for, my question is how can the pledge process take place without consent from the regional or national office? If there were any problems with the paper work, it should have been caught before the process went too far. Also, did the national office give you an explanation or reasons for being denied?
