Based on my personal experience today, the answer is yes (not that I mind all that much).
I found these forums through a Twitter link and so I perhaps should have expected that @ContractJournal would be likely to use Twitter to re-send juicy snippets and tempt new users in.
But it is probably worth asking Janie and the team what guidelines they have in place for this? I assume anything in the public forums is fair game, but it would be good to know where and how comments might be used (eg: on Twitter, in the print edition of CJ, on the CJ website, etc)
