Is there a way to set a cookie to a users machine that will remember his login information as well as his preferences for which ever theme he likes to view the site with?

I have over 1100 registered users at vmoa.net many of them find it a hassle to have to always type in their passwords and then switch to a different theme of their liking they want the website to remeber which theme they like or used the last time they visited.... The default theme was choosen by the president of the organization... I am adding alternate themes as they are suggested... I am only the webmaster... and can only implement technical changes not content...

I don't know whether theme choice is stored in a cookie. If this is the case, you could make the cookie last forever just modifying a line of code (whatever line of code set this cookie, that is).

Storing in user profile involves db modification and minor hack of the core.

where is the cookie file i would need to alter?
