Need pointers on the best method to do this....

[jwocky]

Ok, I want to attach a variable to each user called 'userage'. When a user first enters the site he will type in an age and then whatever page he visits, be it the forumhome, showthread or forumdisplay, this variable will follow with him, this should be functional with logged in and non logged in users.

What would be the best way to do this, I was thinking that would be something a cookie would do, but I dont really know how the cookies system with vB works.

Before I set out and try to learn it the vB system I wanted to get any pointers/ideas on hat the best way to do this variable passing throughout the forum for each individual user for each session?

thanks!
