>> Description:

TM Make plenty of pointless changes to their site.
Previously when you are viewing an action listing, the path to the category the auction
is listed in is displayed as a link form just above the auction title.

EX.:  Home > Computers > Desktops > No monitor

clicking any part of the link would have taken you to the associated category directory.

With the new change, if you click on an auction link from within a members listing pages, the
catagory links from that auction listing will only display auctions from that
particular member not all members as it used to do.

EX:  membername > Computers > Desktops > No monitor

This stupid change has annoyed me long enough to create this greasemonkey script.


This script will not run on following categories as they are not effected by this change
(1) Trade Me Jobs
(2) Trade Me Property
(3) Trade Me Property
(4) Movies-TV

// There are two selectable options available this script can perform:

// 1 - create another link below the member only breadcrumb which will list auctions from all members.
// 2 - replace the member-only breadcrumb with the full path breadcrumb.

//   Edit the line below these instructions to set if you prefer one or two  breadcrumbs displayed
//   set the number in the line below to either 1 or 2. 
//   e.g "var NoOfBreadCrumbs = 1" to diplay one breadbrumb or "var NoOfBreadCrumbs = 2" for both breadcrumbs.
//   ensure the line below remains EXACT as described above including sentence case and spaces.
