The other reason I agree is because my 17 year old son downloads freebies from here and has gotten a virus on his system from a link one day...not good at all.

Well, that explains it. I was actually wondering if there was an incident. I am sorry that this happened to him, but it should not dictate Renderosity's direction. These things happen. Most if not every other 3D Poser site has a disclaimer that you enter an external link at your own risk. There are free antivirus programs (esp. Malwarebites) which can prevent most of these cases. Make sure he remembers to reactivate them after playing or downloading games (some free game software is prevented from running by antivirus software) There are free browser security add-ons, as well, at the Google Chrome Apps place and Mozilla add-ons site. You can also use a firewall, though it's a pain in the butt and has a learning curve.

I am now putting money in some other vendor's pocket instead of a vendor here at Renderosity.

So? See my previous post about the competition. TPtB of this site (I am referring not to the admins of the forum, but the webmasters) need to clean up their act and make the Renderosity Marketplace competitive again. That way, this will result in more people uploading freebies and participating in the community, here, which brings customers and site traffic from those who do neither of those things. Right now people are spending at other stores because they offer more-- better deals, and NOW, a far better community, which allows people to post links to off-site freebies and tutorials. I suspect that perhaps a feeling of helplessness over the PtB's decisions for the site and marketplace might be causing you guys to try and fix it in the only way you can, but these efforts are making things worse.

I am also unsure why vendors put their Freebies at other places as we do not limit the amount of Freebies one can post daily so I would think/Hope they would put all of them here for our members to get use of them.

Some people don't like the fact that you have a "must be Winzipped" rule. ShareCG allows rars, 7z's, and non-compressed downloads. That is just one reason.
And I can't remember, but doesn't Rendo have an upload size limit. thus forcing people with large files to split them into multiple downloads? I can't recall for certain, but that would be reason number 2.
Number three is that some people have personal websites that include their downloads as well as a blog and/or tutorials, which they may want to direct traffic to. Number four is that some people use Sharefile, Dropfile, etc. to upload their links. This saves them the time of uploading their freebies to multiple sites such as their blog, someone else's freebie site, the Daz Forums, and Renderosity, for example. Number five is that some people have a personal marketplace website E.g. Pretty3D's Artraiders, and may want to direct traffic to it. This is almost entirely a thing of the distant past, of course, since it is no longer lucrative to do this, so people almost never do, anymore.
