I'm the admin of the site, sorry for all the confusion.
Tools & Design, as you seem to know, is down for several years already. The hosting provider stated what I was doing was illegal.
After some time I decided to register a new domain, changed the old layout, squashed some bugs etc.
A couple of days ago I also rewrote the scripts "validatemail.php" and "userscore.php", the funny thing is that remoteupdate.php was still active all the time.
So after I was finished I contacted WeChall using the contact form, I still haven't gotten any reply, so decided to check out the site and stumbled upon this thread that was updated recently to my surprise.
In a nutshell:
- Tools & Design(tools-and-design.com) doesn't exist anymore, it's now THC Hack Challenges(hackchallenge.net)
- all accounts from the old site are still there
Also, in the near future I'll host hacking tournaments on this site where you can win cash prizes(PayPal).
Hope I made some things clear. ;)
