WHY do not i show some responses in the discusion????

Yeah, I guess that has to do with mylot upgrading their system. When they do that, some responses get delayed before they get finally posted.

I think it happens with all of us. Whether it be a response back to one of your discussions, or a New discussion that someone may have started there could be many reasons for this. Maybe for some reason the discussion or response was against the TOS and myLot felt it worth removing, or maybe the person was just recently banned on here, or left here by choice so these may not be able to be responded too anymore as well. But in reality you will never really know unless myLot told us all of this.
