List some pages, and I'll give you a URL which will choose one of them at random each time you visit.
You can use this as your homepage or link from your own site.
Beware that your list won't be kept forever, and eventually will vanish without warning. If you keep a record of your list of pages, you can always make a new one.
Allowed characters are: a-z A-Z 0-9 . , : / \ ? = - + _ % $ & # ;
Anything else will be stripped out, but &#nnn; codes should work
if you need any disallowed characters
