Not really aimed at you in particular Chris, no.
It's just there seems to be a bit of a trend on the forum at the moment were the official terms are being encouraged - (There's another active thread concerning OSD badges which doesn't really seem to be reaching any sort of conclusion about terminology, official or otherwise, and in the case of one new member he said he has found it a bit confusing).
I wasn't aware you were writing a book and I totally agree that a glossary of terms in that book will be very useful, but on the forum, were alot of us are set in our ways and find it difficult not to use the 'Slang', who more often than not are exchanging views and chatting about experiences, I just thought extra terminology would confuse even more so.
I hadn't considered that experienced collector's used anything else, I just thought these terms were used by everyone.
And of course, at 42, I might just be plain old fashioned !!!!
Let me wish you well with your project, Chris.
New badge books are always welcome.
