Just to agree generally with Will, I can't remember whether it particularly applies to clubs in the South East but there are certainly some that neglect to put the full address of the venue in an obvious place or include it all (now that would have been fair enough in days gone by for licensing reasons etc but these days I assume its because they assume any potential visitors would know), the other neglect I find is failing to link to forthcoming artists or include a description which would (imo) potentially encourage new visitors.

Personally I think the Ram Folk Clubs site is a very good model and even includes very detailed directions including ones for non car drivers (we do exist)
