Here is something I had not seen yet that others may be interested in.
DASG has set up some new grammar explanation pages here -
https://leacan.gla.ac.uk/leacan/
-and there are three recent DASG blog posts on grammar.
https://dasg.ac.uk/blog/329/en
https://dasg.ac.uk/blog/331/en
https://dasg.ac.uk/blog/332/en
I know I always like to get a grammar explanation from another point of view! (Really!)
