[Pharo-users] Slack Invites doesn't work correctly

In the milestone release of Pharo By Example 5: "Pharo is also active on Slack - a platform for chat based on IRC (http: //pharoproject.slack.com), just ask for an invitation at http://slackinvites.pharo.org. Everybody is welcomed." However, http://slackinvites.pharo.org goes to what appears to be an invalid page. How can a user get access to Pharo on slack? --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus
