I'm glad you mentioned the e-mail notifications. I was wondering why I wasn't receiving any. Now at least I know I'm not the only one.
Regarding your question, I'm no expert on this but I know it would be wrong to wear it if it's an official badge - even if it's on a chain, which it shouldn't be anyway. If it's just monogram letters, I don't think there would be any problem with that.
Now someone will come along and tell me I'm completely wrong.
