How to contact Arenanet?
Depends on what the topic/issue/concern is.
They have various emails for various topics. For example, ArenaNetRecruitment@arena.net if you’re looking to apply, or Exploits@arena.net if you’ve come across an exploit.
If it concerns something in-game, opening a support ticket should offer you the greatest breadth of options.
Forums@arena.net if it’s a forum issue.
ANet may give it to you.
Depends on what the topic/issue/concern is.
It’s not related to technical issues or applying for a position, I would say just general inquiry or offer.
If you have an idea for a change or addition to the game the way to contact them is to post it on the forum.
I can’t find it right now but somewhere in the legal info they actually say they will delete emails with ideas for the game and return letters unopened. This is because legally the idea is your intellectual property and if it appeared in the game you could charge them for it. They’d have to either pay or somehow prove (in court) they came up with it independently, and even if they can do that it’d be a huge waste of their time.
Whereas part of the agreement we all accepted when we started using this forum is that any and all ideas we post become Anet’s property and they have the right to use them without paying or even acknowledging the people who came up with it.
