While I don't agree with limiting community interaction based on character level, keeping this up while most of us are unable to try and fix that is unacceptable. If I can't log in, I'd at least like the courtesy of being able to communicate with my server's community to try and organize events and what not.
Feel free to go back to the arbitrary limitations once the issues with server capacity are fixed. Until then, drop the limitations and stop double penalizing those of us who can't log in.
