If you're familiar with the books and movies I'm sure you can figure out which answers you'd need to pick to get sorted in a specific house. If we get to pick the houses ourself, it would defeat the purposes of the sorting hat test what's Hogwarts is quite known for.

That way it will become a competition if someone's being mentioned and people might abuse this function in chat.

Sending one owl gives you 5xp, posting one post on a topic gives you 5xp, every comment you make in chat gives you 1xp. Every assignment you grade gives you 10xp and every assignment you hand in gives you a variety of xp (depending on what grade you get, you can see this in the grading guideline on the website). Also you will get xp from Peeves Mocking Corner.

If I'm not mistaken, there are no other ways to gain xp for leveling up then this ;)

I sincerely can't wait for this function to be introduced, I have no additional feedback but I really need this :')

Then make it editable and for Prefects/staff members it's possible to see the earlier editions of the wall post :)

In my opinion the website is perfectly responsive for people to use on their phone, if you're having any technical problems with the website such as internet being slow. You won't find any difference in having an application, as it will requires just as much internet connection ;)

I love the idea. It's now possible to buy 6 months of VIP and get an additional 500 galleons/gold dragons or whatsoever. It would be nice to be able to just buy galleons. For me as a graduated member who's not allowed to make any homework and is very limited in homework to grade, this would be an excellent solution.

This sounds like a good idea as I'm at work during 2 of the 3 meals a day and most likely asleep during the 3rd.

I believe if you buy the pensieve you are allowed to use it in topics and you can also win an additional status where you can use the pensieve in topics. I believe it's only possible to buy a number of pensieves over the website so in that way they will still be unique.

I could be mistaken by this, but this is what the headmaster from EU told me when the website had just opened.

No, Witch Weekly actually is a magazine that also exists in the Wizarding World :)
