Board Game Arena

I may be missing something really obvious - where are these guru pages?
I got the notification I had been removed - never knew I had been added.

Thanks

If I have a black wildcard - must I play it or can I opt to take a card?
There have been a couple of games where I'm down to two, play a swap hands for example and the next player immediately goes out.
Rules PDF does not mention - just checking if this is "bad form" or not.

Is there an option to give the solo button a keyboard shortcut?
Annoying when you are down to three cards that include a double - trying to quickly play the double with a solo click between,
