It'd also be useful to know, when a session is included in a list of a local website, does that get counted as advertising; and again, when newspapers or magazines have free lists of what's on, the same question.

Does it make any difference whether the people involved in the session have done anything to draw their sessioin to the attention of other people or not? (For example I will put up details of where and when sessions are likely to take place locally, even when I'm not one of the regulars, and noone's asked me to. Am I putting people at risk of the licence cops?

And also, since I gather (from Gareth?) that it's illegal for councils to make any revenue on this, over and above the expenses, how can one check that a council is complying with the rules in this respect, and thta it isn't being used as a revnue maker?
