Have you heard of the website meetup.com? A wide variety of events of an offer and many of them free to attend and no membership required as the website makes money from the group organisers. You just need to register with an account from a registered email address.
Here are a few groups I thought you might be interested in offering general social events that many different people attend. Over 35s who like going out - Trivia - Live music - Dancing - Pubs and bars www.meetup.com/Over-35s-who-like-going-out
