It's very simple, really: The roster of Member Clans got updated and inactive clans were removed. You can read
Devdas' post again, that's pretty self-explanatory. Nonetheless, here's a sum up:
All inactive Clans were to contact us in one of 4 ways, and had over 2 months to do so.
2 weeks after the deadline, the roster got updated:
Inactive Clans who failed to contact us were removed from the roster of Member Clans.
Therefore, the representative of these former Member Clans had their forum access adjusted to regular access.
If Aethyr Knights re-joined yesterday, the changes should reflect soon. I could not attend yesterday's session, so as soon as I can get the logs, I'll check this out. But you will have to be patient a little, as it will not be immediate

In case you missed it, Pheats announced changes that will affect the CoT, the Newland City Council and the Board of Directors, all.
You can read the post that Pheats made for details.To reflect these recent changes, the Council protocols have been updated. You can view them
here. That should help you get up to speed after your absence.
Ok I checked the links but still not sure what is going on.. haven't had access fixed and still don't see us on the member list..
If you still have questions after this, you can post again here and either the Staff or the Council members can try to help you in clarifying all this.
Hope this helped,
