Is there a Thymeleaf room on https://gitter.im/ ?
I didn't seem to find it, otherwise, I'd like to suggest the developers create one and provide a link say here or on Thymeleaf web site.
That can help the community find and answer questions from other Thymeleaf users.
And leave this for the more 'formal' questions.

I think there are a lot of 'cheat sheet' sort of questions for thymeleaf, a chat room could help with that.
And maybe make a cheat sheet for thymeleaf as well ;)
