Can someone help me? I don't have a Christmas tree and I don't have the link. Please help? Oh and if this is in the wrong forum I'm so sorry T-T

http://subeta.net/explore/luminaire/tree/ You can also access to it from the news page, at the right side of it.

There's also a link on the News page under Current Happenings (that section on the side).

Thank you I wanted to change my tree

You're welcome :). There at the tree page, there's everything to help you to get, add and know any existent ornaments for your tree.
