www and non-www covered, but what about other domains?

.org, etc.

Having read the threads on canonical / duplicate content issues here, I'm wondering if the other domains we have registered but don't use could cause problems.

Here are the results that appear in a browser:

[ourcompany.com...] (preferred domain in Google Webmaster Tools) PR5
[ourcompany.com...] displays our website with PR5 as above

[ourcompany.org...] displays our website with PR0
[ourcompany.org...] displays our website with PR0

[ourcompany.co.uk...] displays our website with PR0
[ourcompany.co.uk...] error - "domain name does not exist"

The re-directing is done in a console at the domain registration company, so I don't know what code lies behind it.

The question is ... Is there a danger that Google will consider we have created duplicate content on these domains?

Uh Oh, I had Google Toolbar on ... I hope I haven't alerted them to start crawling those domains.

Thanks in advance
