This is taken directly from NC as its a lot to explain so better to let the creators do it .
The creators of Havenhollow proudly present its 2nd holiday installation: Mingle.
February 1st we open our interactive hud-based event. Complete the Mingle hunt with your HUD and receive access to some amazing prizes generously offered by some of your favorite designers!
Mingle encourages you to do just that! To complete some of the HUD’s hunt tasks you will need to find someone to do them with! This is your chance to make memories with new friends and old.
The fun won’t stop there with a transferable item gift shop to pick something up for you and your sweetheart.
If you don’t have a sweetheart, you might find one at the Mingle Date Auction. Gussy up and get ready to Mingle!
Event Duration: February 1 – 28th

• When you arrive at the Mingle sim, you will be offered an official event HUD. Attach the hud and follow the glowing arrows to begin your journey.
• The HUD acts as a cell phone. 20 of your cell phone’s contacts (featuring cameos from your favorite brand owners) will periodically text message you a suggestion, hint, or tip on how to make your night a memorable one!
• Tasks are disguised as text messages, most of which need to be completed with 2 (or sometimes more) people.
• Successful completion of all 20 tasks will grant you access to prizes!
• Tasks are timed. You must participate for the specified duration to receive the next task.
