[otrs] Having customers update their phone information

As of 1.1.2, I added the phone information into our database and now require all new users to add that information. But we have about 500 users who we would like to have update their phone number. Is there any way I can add that field to their preferences page and make it editable by them? ********************************* Jake Covert Infrastructure Analyst Electronic Data Systems PSIC Support Group (586) 986-9698 Work (586) 518-3859 Pager http://www.eds.com *********************************
