Simenhancer.com was created by Rick Halle, which hosted useful paid programs for managing objects, skins, and other useful tools. While the website is still working, Rick doesnt answer any emails or facebook posts anymore. Another thing to note is that while you can still do a Paypal payment and get a serial number to unlock the programs, these serial numbers are based on a system id. So if you ever need to replace your computer you would need to contact Rick to get a different serial number for activation. And from what Ive seen, that will not be possible. Site seems to be using an IIS host with minimal link rot. Most links seem to be on the webarchive if needed.

It does have a trial run, so if you really needed to you could install and use the trial. Otherwise these have limited use.
