There are clubs that plan their own events, house teams, or the official plot team will do that themselves, so it does not make a ton of sense to have this be a feature for all users. :)

Another good idea at it's core, but there would be far too many clubs on the club page, and how would you price it? $50,000? It is too hard to moderate individual clubs if users can simply wait out the interest in the bank on one account, then buy a club with this. You can, however, suggest specific clubs to be available on all sites if it related to directly benefiting the site.

This can be arranged by your individual HoH, or HoH equivalent (Cherry Colored name), as they are the main editor of your house pages. I would discuss this with them. :)

This is a bad idea, as management, and on occasion regular staff should be the only ones able to see the plans for events, class deadlines, BS deadlines, and team plans. Having a Calendar Page is really up to your MoM (Minister of Magic, or site Equivalent; Dark Green colored name) who can put specific events on the user page, but it is likely that it is already there.

This would not really get off the ground, since there is already a "sort by year" option in the Marauders Map, or site equivalent.

User Statuses can be found in each site's Status Book in their equivalent of the library.

These ads are largely removable on every site that I am on (a good portion of the English ones) and have multiple "X" or "Close" buttons. Also, VIP or AdFree are very feasible if you have access or the ability to pay online. VIP is very much worth the extra few cents, if you get the chance!

Videos from youtube are good if you are referring to having background music, but and entire video created, planned, and coded into an article or page by a single team would take far too long to do, and if it doesn't rest on the shoulders of those team members in plot, or otherwise, does that mean it has to fall to the illustrating team? Seems like too much for too little.

I translated using google translate, I am sorry if I misinterpreted.

On many sites, that is the responsibility of the missions or plot teams to control and conduct "evil" NPCs, as they often relate to events only.

While this is a wonderful idea at its core, there could be a lot more harm than help here. HoH/HM/MoM would be able to send Direct Notifications to users, and if given to all management, this would be a likely lot to code to restrict to teams alone, and if in any case a mistake is made, or a harmful message is sent, it is send to the potential thousands of users the memebr of management is in charge of.
