Welcome!
Ditto the other replies.. . Hanging around Harnquist the smithy is another good way to meet especially crafters and hunters. Lots of players sell their loot to Harnquist and are happy to say hello and meet other players in character. Lots of crafters do their work at Hanquist's too, as well of course as the smithies in Ojaveda, Amdeneir and Gugrontid. Most people will respond!
Look for crafting guilds too in the /who command, after character's name, many guilds indicate their focus in their name, like the Way of the Hammer, or Imperial Trades, or Knowledge Seekers or Explorers. Just ask if you can watch, go with them somewhere, show you where a mine is, etc.
Have fun! RP is great in PS, just ask a question ic and poof! most times you're in a convo before you know it.
