Anything you write anywhere at any time forms your intellectual copyright and even if you gifted it under a Creative Commons licence it still remains your copyright. In reality, however, this is a forum which the public can browse and thus it would be extremely difficult to contest someone else's use of the material in here. In fact, since our members are often the first to report something happening locally we're more than happy as a forum for the News Media to use it in the local press or TV/Radio. The usual approach when another forum or blog copies part of the posting is to acknowledge it, with something like 'with the permission of..'.
