i found a good addon for all new jewelerycrafters who are already bored by all who ask "what can you craft for XY-coloured sockets"
As a crafter just Dowload GEMList
now your customer just gives you a whisper with e.g. "!gems red"
and he/se will receive all possible gems for this colour you can craft..
additional commands for addon users:
You can set some options using /gemlist or /glist.
/glist inc Toggles whether incoming requests are shown
/glist out Toggles whether outgoing replies are shown
/glist autoscan Toggles whether your Jewelcrafting panel will be automatically scanned when opened. DON'T use this if you use the "Stormy Star of Elune glitch-fix"
/glist desc Toggles searching in description. This is to enable searching for Stats like int, agi +heal and so on
/glist scan Manually scan your Jewelcrafting panel. You have to open it first. Do this if Autoscan is turned off and you learn a new Gem
/glist tlock Determines the Spamlock Timer in seconds. Customers will get a msg to wait x seconds before next query
/glist chatprefix Use this to change the prefix which will trigger GemList in whispers to you. !gem will work always though
'/glist version Prints Version Info. Use this before reporting bugs
/glist insert lets you manually insert gems into the databse. this is the "Stormy Star of Elune glitch-fix" This is not longer needed
