Program I wrote basically does the same thing as you do. I tend to be slow at my tabbing and searching

Especially if trying to share answers with my guild.
Popping up a guild just to test may be useful, but if you hang out near Warren (north building in Atlantis Square) you'll see someone else start up a quest in no time. Especially if you do it near reset. Having control of the cart yourself is nice so you can take your time testing though (gets you at least 1 hour to mess around. Not sure if the cart despawns after that). I suppose if you are joining (not making) then it is a no-brainer to go for it. Low/new guilds frequently invite anyone who wants to join.
