(1) Can we have here an upgraded version of # , on ideone C# is 2.8 for example, but here we have 2.0.*? ... waiting 
(2) after sending code by selecting source-file or pasting code into input form we are being redirected to "Status" page... its very uncomfortable...
why not to redirect to "My submissions" page of this problem?
(3) what + we have by using console input|output ? why not to use methods like TopCoder does, I mean classes? equal algos will pass... no TLE with large input data... all languages will be on the same level (maybe).
Want to here your thoughts and ideas.
Thx.
