Actually, our collector community (or club, as it started out as, but a word I am hesitant in using now due to the existance of the Official Club) started up to provide fans in this part of the world to have a more 'local' internet environment to be a part of. Admittedly, that was over ten years ago now, in a time when there were no fan communities outside of the American 'global' ones. Times have changed though, and presently it is conceivable to assume that any country that has Transformers Fans, is likely to have a local fan community. WHich would make it no longer necessary for us to be offering up that option to non-Australian fans anymore.
If by chance we did decide to tighten the restriction to only allow Australians in, it would only affect new registrations. The existing members from other countries like New Zealand and Asia, would still be welcome here, for as long as they feel the need to interact on another country's forum in addition to their own local forums (which I'd expect they all do).
BUt this is a decision that will take a little time to work out. And any changes to procedures here will be announced accordingly.
