I wouldn't bother with pub quiz nights. I used to enjoy a pub quiz but gave up years ago when the only competitive element left was how brazenly one could cheat by googling on a smartphone. Try looking at the Wirral Quiz league
www.wirralql.org.ukinstead, you should find a team based near you. I play for a local team (which meets in pubs/licensed clubs mostly anyway) and the quizzes are fun, fair and friendly, with cup and league competitions to keep the interest going.
