As I wrote last year, Slackware's founder Patrick Volkerding is struggling financially since he stopped receiving money from Slackware's store a few years back. It was discussed that he should probably open a Patreon account and start receiving monthly donations for his work on the Slackware project. Well, it's a fact now as Patrick himself confirmed on LinuxQuestions a month ago.
I'm catching a little bit later, because I was busy myself putting some updates on the site planned since long ago, but I've become a patron yesterday. And I suggest you become one as well if you love the distribution and are still using it. Slackware is the oldest active Linux distribution and your support would keep it running. I personally hope that this would finally bring Slackware 15 out, because I have postponed many package upgrades since Slackware 14.2 is really old now being released more than 3 years ago.
Please, consider becoming a Slackware patron (the account is slackwarelinux), because your support would be important no matter how much you could afford, so the distribution continues to be maintained.
