Today I visited the rankings page.
What I saw there was… there are two "cherry6120s " !!!
Their activity points are exactly the same, and they share everything
with each other, including my beautiful photo.
As far as I know I am the only person who has a twin sister on LingQ.
Could anyone explain why I began to have another cherry6120?
I seem to have a twin on the rankings page as well, but I can’t see yours.
Maybe the problem is that when anyone goes to the rankings page their own username is displayed twice, and everyone else is normal?
What an interesting bug. 
We just want to make everyone feel important.

Thank you for your helpful replies to my silly question! I thought I was experiencing Doppelgänger!
Not a silly question…silly LingQ…but we will try to fix it.
The “identical twins” issue is fixed now, I believe. 
Thank you, Mark. I miss her…
