The biggest problem with the web site is that every time a forum page is opened, the user must wait for the vertical text shifting up and down to settle because of the advertisements on the top before clicking on the desired link.
A left click too soon opens the wrong link, then go back and wait again.
Even if patience is exercised until it looks like things have settled before clicking, frequently a last instant shift happens, opening the wrong link.
Can't the forum be modified to have a large fixed-size advertisement block at the top so all the forum topics below remain at fixed locations, from the initial display to the time when the last advertisement has loaded?
It is understood that the vertical height of those ads are not identical, so place an initial Bike Forum wallpaper that is either partially or fully covered by the ads.
