.
Tip:
When you discover an interesting program which isn't currently available natively
via MX packageinstaller or via synaptic (using only stock MX//debian repositories),
you can post a request in the PACKAGE REQUESTS subforum
.


Not necessarily limited to sites that host downloadable linux / FOSS software
mention sites that review or otherwise raise awareness of open source software titles
linux-apps.com {---------- presents a subset (no game apps) of the 6,000+ applications listed at http://www.opendesktop.org
sourceforge.net

As discussed in the "Flatpak or Appimage will be the future?" topic http://forum.mxlinux.org/viewtopic.php?f=108&t=42127
pasting found-on-the-web commandlines containing "wget... sudo install" (or "curl... sudo install") to your terminal is a Really Bad Idea !
