Slack is a private chat system for closed groups. The TFTTF Slack was originally conceived as a private group for listeners of the Photography Tips from the Top Floor podcast. I have since opened it up for workshop-specific communication too.
When you come in first, you will see a few channels, the most important being #lobby: this is where you come in first, it's public announcements and things that are of general interest.
There are plenty more channels, initially hidden from your sight, so it won't get too overwhelming for you in the beginning.
To see all channels and join them:
New to Slack? Check out the #sandbox channel, it's a great playground to test things without creating too much noise for everyone else.
Can't find the #sandbox? Click on CHANNELS in the sidebar to find it.
If you want to discuss something in a closed group, you can DM others or even set up your own private channels behind my back.
At this point there is only one rule: don't be a dick, treat others with the same courtesy and respect that you want to be treated yourself.
Same as we did back on the TFTTF Forum.
PS: Slack allows commenting on posts like this, so by all means, let me know what you think about this!
