don't focus on the single part.
volunteer for a cause you're genuinely interested in. try to make friends with people. volunteering is low stress (since you're not expected to be there, and any help is good help), and good way to get to know other people.
join other specific social groups/clubs based on your interests. a photography club, a bird watching expedition, a figure drawing class, a pogo stick dance team, a board game enthusiasts group, etc.
the more you put yourself out there, the wider your reach, and the more likely you are to meet a lovely single lady you click with. if you've had problems specifically seeking singles the next thing to try is to not specifically seek singles, but seek people.
Seaweed makes a lot of sense to me, and I believe she has a great point.
