My latest scan of LLL.in shows many thousands left. All premium letters are gone (abcdefghilmnoprst), and "good" combos (all alphabet except qxyz) are about 70% regged.

By the way, I have a few premium combo LLL.in for sale at NP and DNF for near reg fees. One of them is IPH.in --if interested, you can search for that combo to find the thread.
