It's still week 11 for a few hours and there is still a cover over the portal in portal park here:
https://maps.secondlife.com/secondlife/Portal Park 1/158/76/54
The portal is visible under the cover but there's no way to interact with it that I can see.
I've submitted a ticket, sent an IM to Abnor Mole (who is the owner of the Portal Cover Object), reported the blog post and reported the object I haven't heard anything back from any of these attempts to communicate with LL.
Has anyone else collected the gift? How did you do it?
