Actually, the problem is the software is not correctly handling the target= part of the anchor tag; it is escaping the interior quotes which causes the funny display. Removing the target= allows the basic anchor tag to work OK.
By the way, target= causes the link to open a new window so you still have the old thread alive instead of having to return to it via the back button.
I can't change the golf ball mortar contest entry because the thread is locked.
