I'm afraid we lost our original Grammar chat when Google Friend Connect closed. We started this chat, but it was not possible to keep up to date.
If you would like to see it revived, consider becoming a Patron Support the Network support us.
In the meantime you can use the forum or our Live Chat page to ask us to clarify (or maybe even fix) something you've read on the grammar pages, or write about any points of grammar that we haven't covered yet. Look forward to hearing from you.
