Beware!Newbie account with a suspicious login form asking for username, pw and email. Then nothing happens after registering. This has all the makings of a phishing page. "submit query" is the default name of a form submit button without a name and the page code is abysmal.
If you entered your info, and you re-use passwords across multiple sites, I'd suggest you change them now.
<br>Password: <input type="password" name="password" />
<br>Email: <input type="text" name="email" />
<br> <input type="submit">
</form>
It certainly is a phishing site.Try to send the form over and over with the same values; even using "foobar" in user, password and email doesn't a) cause an error saying email has wrong format and b) at the second time using those values, there's no complaint about those values already being used.
.edit:
Just thought about writing a script spamming his database with nonsense values. ^^
.edit 2:
To kind of prove that this is a malicious site: I just checked the SQL injection, and the error (shown above) shows that the database only has username, password and email fields. There is no way around a user table of a serious dice game having more fields than just those three.
