The script client-edit.pl is used for this purpose. If called
without any arguments, it will display a login screen that asks for the
advertisers username and password. Once provided, the same script will
output a form containing all of their current information, allowing the
advertiser to update it as he/she sees fit. The advertiser can then submit
this information back and commit it for inclusion in the next newsletter.
Note that the form that gets output allowing the advertiser to edit his/her information is a template and can be changed to include only those fields which you feel you'd like to allow the client to edit. The only fields that are not available for editing are those related to the current number of user registrations they have, their account balance, and their impression ratio. Be aware that due to the way that the template is processed, if an advertiser tries to leave any of the fields blank it is simply assumed that no edit is to take place for those fields.
Please refer to the templates section of the documentation for more information on the various templates used during this procedure.
