Hey Nur,
Wonderful ideas, I know Jamaal was also keen on the idea of setting up
a wiki. I think it's a great idea.
I know that
wikia.com offer free MediaWiki hosting, but there is a
manual application process, so it might take a few days to set up.
Or if you / Jamaal have another idea, please go ahead and implement,
you certainly have my blessing.
Cheers - Callum.
