Recommended people (like social network)

[nashlab]

i'm writing a kind of 'dating service' website (just for fun & practice).But right now i'm stuck. I use PHP and MySQL.Every new member must complete 'What do you like (to do)?' question separated by commas:Like this:\[quote\] computing, dancing, reading, TV, movies\[/quote\]and so on.My question is 'how can i show recommended people to someone'?i.e.MEMBER A:\[quote\] computing, dancing, reading, TV, movies\[/quote\]MEMBER B:\[quote\] books, cellphones, rugby\[/quote\]MEMBER C:\[quote\] dancing, movies\[/quote\]In this scenario, A & C have more chances to get along than A & B or B & CI'll appreciate any hint to try to do this real, or your own ideas to solve this. Thanks!PS: Sorry about my english
