Suggestion: when signing up, don't email me my username and password in clear text. If you do feel this is necessary prompt the user when signing up to get permission first. This is a password I use for a number of services, now that it's been sent to me in clear text I feel the need to go and change all my passwords.
Please warn or ask the user before sending a password in clear text in an email!
