So when I opened up the main "all forum" page, I see the last reply in SUP Surfing and Street SUP by user name "JamieMitchell"

Yet when I click on the sub forums, no topics with those replies. Is that because someone from above has removed them, or is it like when someone deletes their own reply within a thread and if they are the last to reply, the Sub forum page still has their username up..

I also wonder if the person using JMs name was actually him???.I have my doubts.

I seen it he was on here asking for everyone to vote for him in a big wave competion and also offering to answer questions in return for people voting for him..
