Well, I have the solution! It's a new spot I created that's created only for that! It's called "Would you join my ... Spot?".

If you want to invite others to a new spot you've created, you probably go for the option of asking in picks or asking in the answer parts. Those things are somehow annoying because a lot of times it has nothing to do with the spot you're in, so I would like to invite you to go to this spot and there you can ask to join to your spot to everyone and nobody will be annoyed ;D

I will distribute this note to many different spots so that fans can post their questions and lots of fans can see your invitation to your new spots! :D
