Mohanad,
I have bad news for you and anyone else who has tried to do this. We accidentally let our domain expire a few months ago (it's been on life support for several years, us paying to keep the server up out of loyalty to our customers).
Someone else grabbed the domain, and put up a phishing site that looks like ours but has an extra "Stay safe and spyware free" add on the bottom right. It is also presumably taking passwords for the party doing it. Godaddy won't give it back to us without us hiring a lawyer and doing a bunch of legal work, which doesn't make sense to us at this time.
I would send an email to Godaddy to get rid of this potentially dangerous site.
Do it soon, as I only brought this site up for a few days.
Jeremy
