Just out of curiosity: how did 〜むず, a structure that basically died out hundreds of years ago, get a page before dozens of other grammar points that people are actually going to see?
maybe someones passion project is classical Japanese 
Even in that case it’s a strange place to start
You’ll have to ask @Asher about that one specifically, although I do suspect it is as @cafelatte says in this case.
In general, going forward I am trying to focus on a range of grammar points across JLPT levels and how common things are (relative to their level) is also being considered. I am also paying attention to how many requests we receive for certain points (some requests are quite popular behind the scenes). We may still throw in a rare something or other that we think is interesting or not served well elsewhere on the English speaking internet though!
A long time ago there was a request thread for grammar points, most of the ones we were adding are just in order of when the requests were made from there. We are slightly rearranging the order when adding new stuff now, though.
Hi!
Whilst reading, I’ve just bumped into the auxiliary verb やしない. It was used together with 絶対に in a thought of one of the main characters, who is desperate for a thing not to happen.
I didn’t find it in the grammar and was wondering if it has any merit for it to be considered.
Thank you!
This one is on our list! Actually, it is a fairly popular user request so I will see what I can do about bumping the priority of it a little.
Hello,
I think there isn’t any grammar point for “でおり” (as in: 東京に住んでおり、日本語を勉強しています。)
It would be nice to have it so I can add it to reviews.
I believe this is already on the list for consideration (I’ll double check). At the very least this is definitely on my radar and something I want to see if we can include either as a grammar point or somewhere in Topics.
I would love to see わけもない as a grammar point or a note added onto わけがない
I cant find much information about it online but it just came up in FMA
抜かせ!
教会内は私の直属の部下だし
バカ信者どもの情報操作などわけもない
Apparently here わけもない is an idiomatic adjective meaning easy to do
I can’t find a vocabulary entry for わけもない either tho so maybe just that would suffice?
Hello.
I found that the following grammar point is missing:
V(る、ない)+ ことが多い
Also I found ただし as vocabulary, but I think it should be a grammar point as well.
I think your example of でおり would fall under the formal conjunctive here 連用形 (JLPT N3) | Bunpro
Because it comes from 住んでいる, and you can’t cut that down to 住んでい, you have to change it to 住んでおり.
I don’t think this is written anywhere on that page though.
