4.000 solutions this month?

[Richard]

I have seen in the main statistics of our Portal that we can have a record this month. Mainly thanks to Berni's Advents-puzzles, we are close to 4.000 entered solutions this month: it can become a record.

I have planned to publish 4 puzzles coming friday, of which 3 are not so hard, so that might be contributing to an end-sprint of this puzzle year as well...

Let's go for it!
