If you received a message from the user robertlechter...
If you received a PM from this former user and clicked a link that he sent, you were sent to a spoof site that looks like THT.
If you logged in on that site you need to change your password IMMEDIATELY.
Several accounts have been accessed from a Nigerian IP address recently so it is believed that some members have done this.
Also, if you use the same email/password combination for any other sites, especially financial you need to change those as well.
