The one linked below works for nearly all the sites, but you need to create an account (it is free). Once you do you simply cut and paste the hand that you want to convert into the appropriate box, select the 2+2 format, and hit the convert button. What comes out is the hand converted to display on this website which you can cut and paste into a post. It won't look like a poker hand in the output window, but onces its posted (or previewed) it should look good.
