WL recruitment!

Hello SGers! It's November, and after being super inactive for the past 2 years(?), I've decided to make a small train on my birthday (which is on the 26th). Besides the train, there will be a special GA for my WL, since I rarely do those, and to give back to those who really mean a lot to me. Now, that doesn't mean I'm excluding the rest of the community, because you still have the train :)

At the moment, there are 3 categories of people in my WL:

• Users who made awesome events, or GAs in the past
• Users born on November that were recruited on my previous WL recruitment thread
• Users who have been kind to me or others that I deem worthy.

So this year, I decide to recruit Users who have been on this site for quite some time, and have also been checking on discussions regularly. There will be a puzzle for you to prove this, and I think my target WL audience will know how to answer my puzzle easily.

Thank you and see you in a few weeks :)
