If we can't afford to pay Oracle for a certificate to publish our web-client, why not take down the option to use it? It makes no sense to have that option, and anyone new to our community may think the server is down when attempting to use it. At least until we can pay the exorbitant fees to have it through donation, everyone should have a client to play.
Maybe we should follow Jagex's example and stop wasting money on a web-client certificate altogether.
