Really weird, just today I had a random thought “I wonder if that website where they gave out temporarily 100%-off commercial software is still around” so I searched for it and found the name and saw that software. Neat how they’re still around after more than a decade, still offering desirable software like that. Weird how I see it mentioned on this forum hours later, after not hearing about it for the last ~12 years.
If you have enough random thoughts then some of them will come true.
thanks for the link @mcallis
