My idea...

[metrohenrik]

Let me start saying, i am not able to programme anything. I am a absolute beginner in this stuff.
But my idea: Make users timeframed, like the articles.
One off the options i can make for one article, is make this article public starting [date] ending [date]
Why not for users. User A have acces to this level starting [date] ending [date]

Just to anyone to take it further.

You can probably already achieve this by using a membership component. It's not something that a lot of users are interested in.
