Open to Pro's with fewer than 400 points..
Answer removed. 
What are those new rules?
As I have only few minutes for this website during the week and I come here to try to solve something my answers/guesses are instantly removed. Gentlemen, what a heck?
There are already only few active members on the forum - one posting (better to say - reposting old ones) puzzles and only few who still spend time trying to solve them.
How many active rookies we have? Do we still need any new members / rookies and this section at all?
Why do you want split pro section? If so, create new level - super pro, master, guru, etc.
Summa summarum: once upon a time AutoPuzzles was a nice place to spend time and identify mysteries. Now google images search and attitude of members ruined all the fun and spirit of the forum completely. As there are less and less interesting things to see and to do, I just wish you all good luck and tell you goodbye!
