I have now been a member for 1 year, 3 weeks and 2 days and still no achievement, neither can I find the link to preferences :/

@.Snowglobe.

Just click on the Button on top that says "Prefs" - that will take you to your preferences where you actually should receive your achievement. If not I'd suggest you to send in a Ticket.

Ahaa - that was where it was hiding xP lol
Got the achievement! Thank you C:
