Hi Sol. I have a long list in a freebie newspaper in front of me of different clubs on the Costa del Sol. There is everything from American Club of Estepona, American Club of Torremolinos, to British clubs and societies, to jazz societies, to flower arranging clubs etc etc.
They all appear to have submitted just telephone numbers and there is no sign of any e-mail addresses or web sites. Let me know if there is any specific club or society that interests you and I'll let you know the relevant phone number.
There is no web site for this particular English language publication, El Pregonero, or The Town Crier, but you could always try looking in the on-line versions of other free newspapers out here, such as The Entertainer at
www.theentertainer.net or SUR in English at
