No, slack free plan only allows 10000 messages to be saved at any one time. Nothing to do with user limit.

Unbelievable that a service like this would change the key part of their platform without even checking the pricing page to see what free plan restrictions were...

EDIT: I stopped reading after the first paragraph, looks like there was a user limit issue too :)

Except if you read the whole post, he ran into a previously undisclosed explicit user limit. The client was crashing. Slack ideally should warn you if you have too many users, before the point where the client crashes and the backend fails to send messages.

Even if they hadn't, the 10k message limit is well publicized and would have forced them into an insanely expensive pricing model.

Slack's pricing model and the ad copy of their website makes it obvious to me that it's a communication tool intended for small teams, not a chat room for thousands of users.

But who runs a chat with 5000+ users? The signal to noise would be insane. If each user posted 1 message per hour, that's 5000 messages per hour. For a group that size it seems like Twitter makes more sense. I can't imagine 5000 people needing real time communication. Kind of the mother of all edge cases for a team chat service.

The 10,000 message search limit probably limits this realistically to 5 or 10 person teams. I would think I would want at least a week or even a month's worth of searching (ideally indefinitely, of course).
