ZSell is a lovely little addon that allows you to link items and crafts through macros.
Use: /zsell <target> text with links as [<id#>]
Target can be GUILD, PARTY, RAID, YELL, or SAY.
It can also be a channel number (2 for trade).
Or the name of a player you want to whisper.
You can also link crafts by placing an "e" in front of the craft ID.
