You don't have to add anything in the meme comment now either!! I've always had to type something in and change the font to 0 or it would tell me my meme was empty. :-) I may have just assumed the memes worked the same way and never tried to submit it blank without doing it that way though.
Still works on memes, just not meme comments. I assume Socrates is right. I guess the memes have always worked that way and I just thought that since you have to do the font to 0 on comments you did on memes as well. I am going to look for the blank meme comment I made yesterday though LOL it's driving me crazy I know it let me comment twice yesterday with blank templates!!
