English, England furs, no difference. One just includes non-furry members from england. BRITAIN is all of the UK and such, but the way you said it made it sound an awful lot like you meant for them to just post in that thread.
The Calling All English thread was originally for ENGLISH furs, but the others all got shoved into it because of cultural ignorance.
And with the Australia one, and all those other countries you mentioned, they're pretty big places and could do with being broken into states/provinces, but I'd say those people would feel much the same way that I do, in that a thread about Victorian or Melbourne Furtopians would just get locked and told to go into the Australia thread and etc for other countries.
Edit: Kobuk, I'm not the only one that feels this way. My thread was originally a reply to the Scottish topic, but it was moved here by a mod who thought it was a legitimate issue, and I've been contacted by another who also agrees.
