Hi,
thanks for reporting this. I am having some trouble ensuring that only the correct tracks appear on the members site "Submitted tracks". This is caused by how the forum member database stores two names, the user id (nick) and the user name (full name). Some of our members have used the nick as author and some use the full name. So, for the members site I use a combination of these two to pull up the tracks, and although noone has submitted any tracks under the name midiwiz, someone has probably submitted one with your other name.
I will fix this when I get the time to complete the members section.
