Why did this happen?
I asked for help from within the ES6 course and then:
Our automated spam filter, Akismet, has temporarily hidden your post in Regular Expressions - Restrict Possible Usernames for review.
akismet sometimes flags posts as a precaution. But I don’t see yours?
Is it already up somewhere? (which subforum did you use?)
Edit: I managed to find your post. I’m not exactly sure why it got flagged/deleted but I apologize for that. I assumed you had deleted it yourself so I didn’t bother correcting the spam flag.
Got someone to help restore it though, so hopefully you can find it here
