Newbie to trading

Hello there..

Iv'e been playing poe for at bit of time now, not so many hours on pc mostly on console

on console trading is via noticeboard in game, it works decent

Welcome on the PC version of the game Morten, have a nice time here.
To answer your question:
1) Go to https://www.pathofexile.com/trade/search/Standard to search the item you are looking for.
a) Switch "Standard" with any other server you are interested in, on the top right of your screen.
b) Switch "Search Listed Items" to "Bulk Items Exchange" if you are looking to trade currency, fragments, oils etc.
2) Once you find it, there are 3 options under the seller's avatar
a) Whisper. This option copies a standard text "@"player's name" Hi, I would like to buy your "item's name" listed for "item's price" in "server" ("stash tab name" "price tag"; position: left "x", top "y"). Then you just paste it using ctrl+v on your chat and hit enter, it will pm the seller with the text mentioned above.
b) PM. This option allows you to pm the seller on this forum.
c) Ignore. This option ignores the said seller.
Hope it helped. Stay sane, exile!
