I don't quite get things around here but anyway how long exactly does it take between the time you register and the time it takes for your account to be accepted?

From the moment you send us a correct account request, it takes some hours up to some days until you receive a mail with a quest. From the moment you send us your reply it takes some hours up to some days until we read it, made our decision and send you our refusal or acceptance. From that moment on it takes some days until your account is activated.

To summerize that it takes about one or more weeks to get an activated account, depending on what you deliver us and how fast one of us can spend some time to look after it.

So after creating a charecter, you go to the account request on the site Illarion.de and press in your info and just wait one or more weeks?

Yep. Create your character using the Client. Then apply, get accepted (hopefully ) and then you should be able to log in with the char name and password you used when you first made it using the client.
