À l'université Post - un poteau / des poteaux (in French from France they probably just say "post", but you didn't specify what kind of French) Comment - commentaire "Comment dit-on" serait la bonne façon de l'écrire, mais je préfére "comment qu'on dit" (mais ça peut être très regional) Verb "exciter" is mostly used in a sexual context, I'd recommend "J'ai hâte de lire vos commentaires"
Sinon, bel effort! Continue comme ça!
Definitely, why wait? Free speech is free speech, but there is demonstrably nothing about this specific free speech that would make it valuable to the community. Keeping them around will just turn this instance into a nazi bar.
