Super quick and dirty Python script to bulk invite ALL users in a slack team to a specific channel. We need to do this regulary with Counterparty when we create a new channel that everyone should be in, or move things around.

To use:

• Install the slacker library via pip
• Get an API key
• Create a file in the same directory as slack-bulkinviter.py called apikey.txt, containing your API key
• Execute the script, passing the name of the channel where all users will be invited, such as ./slack-bulkinviter.py mychannel
• Sit back and let it do its work
