What does the software or service do well? Great way to communicate with people who you collaborate with. Real time commenting and feedback is great as well.
What does the software or service not do well? The UI is a little clunky...it can be difficult to attach files at times. The notification that there's a message does not stay on the screen long enough.
What do you wish you had known about the software or service before using? Nothing really...it's fairly straightforward once you get it set up and get used to it etc
Have you used a competitor to the software or service? If so, how does it compare? I also use Slack and honestly I like that better as I find it easier to use
