I know this is probably not the right place to report this, but I don't know where else I can report it.
On Symfony Slack, a user told us that slackinvite.me/to/sylius-devs is down. Indeed, slackinvite.me seems to be down, that's why we removed it for the Symfony Slack.
A simple alternative solution is to self-host an application like https://github.com/rauchg/slackin but at the end we decided to use a "shared invite" which is a link with auto sign-up. The number of people it can use it is limited, but you can renew it. It should be available at https://sylius-devs.slack.com/admin/shared_invites
Thank you Javier, I had some trouble setting up Slackin but I will try again soon. If it does not work out, I will check the shared invites.
Thanks for the tips, I will keep this open until it's resolved.
In case it helps you, these were the steps that I followed to setup Slackin on my personal Heroku account:
1) Visit https://heroku.com/deploy?template=https://github.com/rauchg/slackin/tree/master
2) Visit https://api.slack.com/custom-integrations/legacy-tokens and click the button to generate a token. (this URL is called "legacy tokens" ... but it's the "good token")
3) In the Heroku deployment, set these two variables:
sylius-devsAwesome, thank you so much Javier, I couldn't find the right token before. :D 馃嵑
It's now available here: http://sylius.org/slack.
