Well, there are other ways to get to a person's classifieds profile than their ad. If you know their username, and go to their profile, you will see a number at the end of the URL. This is their user ID number and it can be exchanged with the number at the end of any users profile. So for example, this is my classifieds profile : http://www.ehmac.ca/classifieds/member.php?uid=5577
If you change the 5577 with dolawren's user ID which is 1248 you will get his classifieds profile.
A little confusing but if you understand how the ehmac website is set up, it makes sense.
