I know that many Wikimania attendees are staying in Egypt a bit longer for sightseeing or whatever.  If you will be in Cairo at anytime after the conference and would like to meetup with other Wikimedians, please sign up on this page or let me know:

I am busy with my university program in Cairo, but will have some free time in the late afternoon and/or evenings.  There are also organized tours (see the booth) if that's what you prefer.  What I can help organize are informal activities.  We could meet-up for dinner, a felucca ride on the Nile, go to Khan al-Khalili, or whatever.
