The ACM-ICPC regionals are coming soon, and everyone is practicing, and for sure you may need to run a practice contest.
So I made a new website which will help to organize and run virtual online contests easily, and this website will support 9 online judges (UVa, SPOJ, Live Archive, Codeforces, TJU, SGU, PKU, Timus, ZOJ). And the same contest can contain different problems from all these online judges. You don't need to install any software, you just need an account.
This is the website link http://ahmed-aly.com/voc and you can check the FAQ page for more information.
If you already have an account in UVa And SPOJ website, you can sign in using the same username and password, just make sure to verify your account, and check your account page to add more accounts and change some default preferences.
Also there is a running contest which contains one easy problem from each online judge, you can register for this contest here http://ahmed-aly.com/voc/Register.jsp?ID=20
If you have any suggestion or feedback, please feel free to say it.
P.S. Check this page http://ahmed-aly.com/voc/Finder.jsp it's very helpful (at least for me).
