Here's an idea. Maybe if they had a website that actually worked in an acceptable fashion they wouldnt have so many support tickets to deal with. the amount of times the pages are unresponsive or take 30 seconds to load is unacceptable from any website. For this to be the case on a website solely dealing with time critical financial transactions is simply beyond belief. 

Surely the very least they should be doing is suspending all new signups until the site is up to speed, but no the problem seemingly gets worse every day. Instead of limiting signups and trying to provide an acceptable experience to the traders their greed motivates them to allow further overloading of the system.
