Re: [Pharo-dev] Discord server vanished!

by Dimitris Chloupis

There was no need, all invite links are still valid. I created a new one for people who had lost the old ones or do not want to search for them. Forgot we have one in the website. In any case no harm done.

Hi Kilon, Thanks for all the effort. One interesting thing that this situation revealed to me is that I realized that I missed the access to the community that Discord provides. Thanks for doing this.
