The Wiki also has all the current rulings I think.
It doesn't.
What, exactly, doesn't it have?
I'm sorry, but I just don't have it in me to go through it and check, and nothing springs to mind now.
When people started doing the wiki (unbeknownst to me), my BGG FAQ - which was the precursor to my rules document - already existed. When I discovered the wiki, I found it a bit odd that my FAQ was not consulted by the people writing the wiki, since that FAQ was the only text that aimed to have all current rulings and clarifications collected. I posted in this forum about it, after checking that indeed several things were missing in the wiki. Nobody responded as I remember - at least nothing was done. I hope you understand that I didn't see it as my job to update the wiki then. I had already done a lot of work. (If they had started adding stuff from my FAQ and asked me for some sort of help, og course I would cooperate, but that's different.) From then on it seemed the two documents would lead separate lives.
Since then for sure the wiki has been significantly improved, but I haven't seen any evidence that anybody uses my FAQ or now my document to update the wiki (or put in the work themselves to go through everything Donald has posted here and in all the BGG Dominion forums as I have done), and from time to time I discover some missing stuff there. The Beggar thing in this very thread is one example. A little while ago there was a thread and discussion about the "dividing line", which had been in my FAQ for ages but was not defined in the wiki. I guess it got added after that thread.
Now, as then, anybody is free to go through my rules document and add whatever they want to the wiki.
