Insert your name and a password that you remember and click "Create Account". You may be asked to receive Slack tips. It is recommended to select "No thanks". Once you do that, you will log in automatically to Vasilis Skarleas Network Workspace. You will receive an email like this one below as a confirmation message.
On the workspace page, you will find out that under the "Channels" section there is a channel called #general (maybe not accessible to you) and a locked channel with your project's name. The last one is the private space from which you can contact your developer, send HD images, text files, etc. Slack can also get used to set up reminders.
On the apps section, there are several 3rd party apps installed in the Vasilis Skarleas Group directory. You can use them by connecting your own accounts and get the advantage of using them like Zoom or Google Calendar.
