I have noticed that people when they put items up for FT they are able to link them rather than typing it all out, If anyone knows how to do this please let me know.

I have tried following the perm link guide/s but they don't seem to be working (I could be doing something wrong).

Any help is much appreciated

Use the guides to get the item number -- should be found using the view source on the character page that has the item (use control - F to bring up the search function)

http://ladderslasher.d2jsp.org/itemHistory.php?i=xxxxxxxx&c=0

put the item number where the x's are in that link

And for HC items you put &c=1 at the end of the address line in place of &c=0
