Have you heard of Orkut - Google's new foray into social communities? Have a look at www.orkut.com to find out more.
I've just found 5 South Africans I have not corresponded with in years there - it's really cool.
If anyone needs an invite to join, let me know via PM - as you can only join Orkut if you are referred by a friend. In this wau, Orkut is one of the few online social networks that remains SPAM free.
