CiviCRM Community Forums (archive)

I've figured out how to send users an email with a link that lets them update their own information (name, address, phone, etc.).  I created a profile that only contains the information I want them worrying about, and that seems to be working reasonably well.  The link looks like this:

http://mysite.com/index.php?q=civicrm/profile/edit?reset=1&gid=16&id={contact.contact_id}&{contact.checksum}

(by the way, what does the "reset=1" do?)

I need two additional pieces of functionality though:
1) When the user get to the site, they should be forced to update their (Drupal) password, and be given the opportunity to update their (Drupal) username as well.  I don't know how to include these values in the CiviCRM profile.
2) I then need to give the user a link they can use later (one that won't expire in 7 days, it's my understanding the "contact.checksum" expires) where they have to manually enter their password (it would be nice, but not necessary, if the link contained the correct username).

Any suggestions?

Thanks!
