Changing Webmail passwords

I have set up some Webmail accounts for my family. Now I want each user to be able to change their own password without asking me to do it all the time. How can I do this?

Thanks for the reply.

At the moment they do not log on to their email acounts. The accounts have been active for about six months and they either use Thunderbird or that Microsoft thing to check their email. I think maybe I have to provide a link so they can actually log on to their account rather than use an external client. Am I on the right track by saying that?

Gee, I fixed it. Did not know it would be so simple. One link to /webmail and there it was.
