guildwarsguru.com auctions question...

i got a question about the website but i didn't know where to post this so i'll just put it here, well heres the question.... um, i don't really understand how the auction system works, so i post the items i want to sell and if someone wants to buy em do i have to meet up with them online for the transaction or is it done automatically?

u have to meet them ingame..u get sent an email with their details when the auction has finished
