First, is posersoftware.com the same company as Renderosity?

If yes, the download page...

https://www.posersoftware.com/downloads

... says this...

The app includes a 21-day free trial period after which you will be prompted to purchase a license and receive your serial number.

But the sales page on Renderosity says nothing about a trial, best I can tell.

Can anyone clear this up? Thanks!
