Hi ThicknRich,

Really appreciate you sharing this script as I find it incredibly useful in our environment. A new manager has seen our Yammer membership jump exponentially, and each day the ratio of "#joined" posts to "real" posts sees the former outnumber the latter by 15 to 1 sometimes.

One tip I do have; in Chrome Version 50.0.2661.94 m (Windows), having added the extension I've found that the next time the browser is opened (next day in my case) Chrome throws a warning about the extension being added and hard-disables it, preventing it's re-activation.

Rather than having to keep deleting and re-installing it each day, I did some research and found that if you use "Tampermonkey", which is a user script management extension for Chrome, to execute your script, it is not blocked by Chrome, as Tampermonkey is a recognised Google Chrome Web Store extension.

You'd think by now you'd be able to tell Chrome what extension(s) you wanted to keep, if they were non-web store ones, like "self-signing" them or something, but hey... sigh

Would you be happy for me to submit your script to Tampermonkey to help spread it around (I'll ensure you are credited and provide a link back to your blog where possible etc).

Tampermonkey can be found at https://tampermonkey.net/ and https://chrome.google.com/webstore/detail/tampermonkey/ [string]

Thanks again and regards.
