I still check in once in a while.  And I've still got some Descent- and Overload- related projects in the works even after I finally released some of my D2X-XL maps last year.

I've been more vocal about those on the various discord channels though.  There's the Descent 1&1/2 thing that's been going on for years.
There's also a 15th anniversary update I'm working on for The Enemy Within that I've got to make some really cool stuff for already, and got me very excited.  Right now it's a solo project but I'm hoping to eventually bring in a few more folks to help with some extra things that I don't have the knowledge or skills to do well enough.

I should probably make a thread for that one sometime soon.

Video's no longer private

FYI, it's coming up as a private video for me.

 Whew, I was scared when I wasn't able to receive the confirmation email since my old email is gone.  Anywho, before that endeavor, I changed my name to just Sapphirus

Yes, where did you get it from, and was it recently downloaded? Because if it was a recent download, it's possible the site you downloaded it from was likewise infected and slipped in malware with the download (though these days, most anti-virus systems are good at alerting such things).

If not though, and you've had the file on the computer for awhile now, then yes, it's almost certainly a false positive.
