Some problem with myLot?

I have had this happen a couple of times when I created a topic from something that I added to my interest list. Since I was the one that created it, it seemed like it took a while for it to get pushed into the system. After about 48 hours it did show up as did the photo that I uploaded for it. I have no idea when myLot does a system merge, maybe around the same time that they update the earnings. If you don't see your topic listed in the section you added to it in 48 hours, send them an email and see if they can give you an official answer.
