Be that as it may, what would it take to get rid of the "registrations" feature for a few months or if necessary, permanently since no one is being '"enabled" anyway and probably never will be?
Not much, if one is a skilled php programmer... a few minutes. If not, it would take slightly longer than it takes to learn a bit of php. The change might screw up the rendering of the page, so add in some extra time for debugging. But it could be done in hours, rather than days, if one has a knack for computer languages and a high threshold for tedium.
Being that technology is evolving rapidly, could some tech geek install some virus with
Well, sure, they can do that on ANY page. Right now, for example, anyone using XP/W2K/W2003 can have their system taken over via a bug in the way their OS handles QuickTime files. There is no patch, only a workaround (which 99.9% of MS customers will never apply), and you don't have to click on anything for it to work, just going to an infected page is enough. (The workaround is here, BTW: http://support.microsoft.com/kb/971778
What makes this kind of exploit especially scary is that it needn't be hosted on a hacker's website, it can be (and has been) posted on big, famous websites that we've all visited. This is done by attacking the website and inserting a reference to the malicious code into their page. The attack method most commonly used (SQL injection) can only be carried out by someone who can post or submit content to the site, so a closed site like this is far safer than one where everybody's free to post. In that respect, disallowing any new members could be an effective security measure, since it excludes new posters who might come here to spread malware.
BTW....What would you say if someone told you if you didn't like Scientology, to start your own relligion? Or if you didn't approve of CO$'U. S. tax exemption, to move somewhere else? Just askin'
Sorry for being grumpy in that last sentence. I'm just going under the assumption that Andreas is doing the best he can with the time & resources at his disposal, and hope that others will cut him a reasonable amount of slack. It's not as if we had any reason to question his motives or dedication to the cause. But if he DID want to turn the site into an online clam retailer, effective tomorrow, that'd be his own business. We're just his guests, not taxpaying citizens.
