I recently received an email from a popular graduate job web site (prospects.ac.uk) that I haven't used in a while suggesting I use a new feature. It contained both my username and password in plain text. I presume this means that they have stored my password in plain text.
Is there anything that I can do to either improve their security or completely remove my details from there system?
UPDATE: Thanks to everyone for their advise. I emailed them, spelling out what was wrong and why, saying that I will be writing to the DP commissioner and will be adding them to plaintextoffenders.com.
I got a response an hour later: an automated message containing a username and password for their support system. Oh dear...
