It is very exciting for me to work on this,i have develloped three application till now on sharepoint 2010. one is sharepoint team status 2010,leave application,timesheet application and the best thing is that all of mine applications are assemblly free...ohhh no need of dlls,in my next blog i will post the wsp as well as code for my application... Really ecma script and object model change the way of devellopment,and sharepoint 2010 designer is as kewl as it was supposed to be,it took me very less effort to create my first work flow with it..
