I like the idea they have on 'eab.abime.net'
The 'Guess the Screenshot'. It encourages communication and feedback and also educates us in some Amiga games that we may have played loads but couldnt remember
(I for once have had my memory jogged by games that that I couldnt remember playing but was mentioned in the above quiz!)
They have a table showing who has had the most questions right.
If we implemented something on here, it doesn't have to be screenshots...could be trivia based inc such trivia as characters, game titles, software publishers etc etc
If someone has already mentioned this then my apologies.
