ZSell

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.

Examples:
/zsell 2 WTS [2516] for 1g!
/zsell 2 Enchanting [e27954]!

To find the ID of an item or craft, use: /zsell [link]
