I was locked out, i couldn't even get RCU to show up on my screen, it took so long that it timed even after 3 tries!, i thought server crashed or something else happen all of sudden. There were no notices of any type saying anything about upgrades or changes to formats anywhere on the site.

I thought it was my PC at first but now i can see 3/4 of the membership suffered from it also, now i'm ok. RCU Admin should post some notices in advance by couple of days at least before they do maintenance or formal changes to the membership...
