I realize this might not be the safest procedure but here's my dilemma: I have a lot of existing members that I'm now putting in the database. I want to assign usernames and passwords to each record. Once a member visits the site, they should have the opportunity to change BOTH their username and password to something THEY want. It seems to me that if the basic program checks against duplicate usernames a mod could do the same to prevent any possible duplicates.
Does anyone know how I might go about allowing the visitor to change their username?
