Slack 90 day limitation? MIGRATE TO PUMBLE ! - no brainer, and FREE of limitations 

I was a happy Slack user... up till a couple of weeks ago when they announced they were creating a 90 day lifespan on your messages! That basically means anyone with a free account will have a massively reduced product. For people like myself who uses Slack to keep track of several important projects which do not make profit, I have had to look elsewhere. I tried 8 different products, including BITRIX, CHANTY, FLEEP... but none offered unlimited Workspaces AND Messages AND Timeframes than PUMBLE. It is the only one that does all the Slack basics FOR FREE FOREVER.
