Ha! Just another of cheez's new screw ups. Some lols have a comments section and some do not. It is apparently random. So if you look at the bottom and there is no comment box, you're just out of luck. The only benefit I've seen so far is that the peeps are messaging each other more! Love you, woman!!
It's always hard to lose a loved one - furry or otherwise. ED the comments have to be done through a 3rd party program. Most of the "old guard" cheezpeeps are not happy and not doing comments except by making new LoLs using the Original LoL to do it - eg: http://cheezburger.com/8792775424
