When viewing an "answer" at Experts-Exchange you get numerous times the text:

Well, this statement isn't true, as the real comments are at the bottom. But when fooled by this and you started paying for the "free" service, you can get suspended when you fail to "close" your questions:

From Netminder, one of the administrators at Experts-Exchange:
======================================================================
Generally, the member gets a friendly, "here's how you close your questions" MC from either me, a Mod, or as far as I'm concerned, a ZAPE. Then, if no improvement is seen, he gets a second MC that is a little less friendly, and generally includes a list of the questions that are abandoned. Then he gets an email saying "clean up your mess or you'll have problems using EE" that includes a specific deadline -- usually a week. If there's no improvement at that point, we suspend the account, which usually gets someone's attention.
======================================================================

A true "userfriendly" site to get your answers from. Besides answers you're drilled into the "close your question or you're suspended system".
Guess from my previous posts it's clear why this "free EE behavioural course" is used at the site. The experts work for "free" and when they don't get points from closed questions, they might go to other sites (like www.bytes.com) where no points are involved.
