We strongly suggest that you do a couple things, since we don't know how many times this has been done already nor if holes exist that can be exploited now:
- If you use the same email/password combination on TheTVDB that you use on other sites, we recommend changing it on those sites.
- We recommend that you use a password on this site that you don't use elsewhere.
- We recommend that you change your password on TheTVDB.
As a general practice you should do these things even without security issues at websites that you visit. I recommend the use of LastPass.com or a similar password management tool to help maintain multiple passwords. Finally, if anyone would feel more comfortable having your account removed entirely from the site, please send me a PM with your email and username and I'll get to it ASAP.
Note that this does not affect the forums, but if you use the same username and password in the two systems, you should probably change your forum password. I'm quite sorry about this.
