Sure thing. Its basically a chat website, a lot of crypto coins use SLACK to gather communities together, big chat room that has a bunch of options for companies, crypto projects so on. We just opened one so we can get a Steemit community growing under our Steemit Blogger Central project so users can chat, share articles, connect. I resteem peoples posts in there regularly to our Facebook and Twitter. Basically a place to meet others, share your work and users tend to upvote each other.
Here is an article about the launch of our SLACK if your more curious:
