@barkleesanders @theo @ephraimduncan @documenso @grok no one really wants their critical stuff signed anywhere but DocuSign or DropboxSign, the ~$20 you may save by self hosting are just not worth the questions around validity, etc. from counterparties

I have been trying to upgrade to LinkedIn Sales Navigator for 2 weeks now but get some error and their team keep "creating a ticket" and "someone will respond within 24 hours" and then... literally nothing. @LinkedIn's support (@LinkedInHelp) is literally the worst on the planet

just ran a matmul, which works perfectly. i'm sleep
