AV 2009-2010 Below Taxable Income

HI , 

I havent yet filled the IT return for the AV Year 2009-2010.
I did not have any income , apart from a little interest on my savings bank account which was only around a few hundered rupees.

So is it required to file the return now.
If so , is it possible and are there any penalties.

Will it be an issue to skip this and continue with 2010-2011 return not maintaining continuity.
 

I would like to get things in order now.

Thanks for your support
