I always get our hosting team (managed server) to set these up, but hate not being able to do things!

I currently run a little bit of php on www.meetinthemiddle.co.uk that changes the "featured venue" each time the index.php page is loaded. It just picks a random record from the db. I'd like to actually make this change daily - and obviously a cron job is in order - but I haven't the foggiest how to do it myself.

I could get the team to do it, but would really like to expand my skills base and learn how to do it.

At the mo, I'm guessing that I could make the server load a php page that changes the record daily - am I thinking along the right lines? And if so, can anyone offer a little guidance?

Cheers,

H
