Daytime activities? (Beijing)

Hi, I was just wondering if anyone would be interested in a group for people who are free during weekdays? I work in the evenings so find it difficult to get along to many Internations events. If there are others out there who are free during the day prehaps we could create a group to get together for lunch or to play some sport? Just thought I would sound out if anyone is interested.
Cheers.
