Bringing back a rather old suggestion, but it would be wonderful if we could chose to close our lumi trees this year. Hiding the tree is not really a viable option as it can always be found via link.
This idea already exists on this thread (and probably others - let me know if you know of any other threads that suggest this so those can be locked)
Since this thread is a duplicate, I'm going to lock it. Please post your support on the thread I linked above and remember that there isn't a "no necroing" rule in Suggestions&Ideas :)
