Wee-slack was my go-to for the longest time but can no longer use it and it makes me sad... The problem with it now is that they had to migrate off the legacy API tokens. You now need an administrator to authorize wee-slack as an application for your organization. Not all organizations are willing to do this.

One benefit of being the admin... Fwiw I was worried about the port/move, but it works very well.

Just switched over to this. Thanks for posting.
