For a summary of what a paid plan offers please also refer to this slack page: https://slidewiki.slack.com/pricing. Our case will be only for the Standard plan. In the alternatives section we should list any idea we may have that could serve our needs without moving to a paid plan.

Pros

Main advantage: already using it, would like to recover old messages already there.

• Unlimited searchable message archives:
  currently we have reached a point where we can't access old discussions

• Custom User Groups to reach a team or department:
  this might allow for bringing non-developers (like trial partners) in closer coordination with developers

• Group voice and video calls, Screen sharing:
  currently we are improvising with whatever we have available (skype, hangouts, gotomeeting) for breakout sessions between team members, it could prove useful to consolidate those in a single technology

• Unlimited apps and service integrations
  We currently use a minimal set of apps/integrations, one reason is that we can't, as the limit is only 10.

• 10GB file storage per team member

• Pricing: according to Benjamin Wulff: there are currently 42 users signed up - cheapest option on Slack is 6.25 eur per month per user thus 42 x 6.25 = *262.5 per month*, *3150,- per year* (because if you choose to charge by month it goes up to 7.50 per person per month) 
• Slack for education: https://get.slack.help/hc/en-us/articles/206646877-Slack-for-Education
  Annual cost per team member, after the discount:
  $12.00 per year — Standard plan
  Kostis Pristouris: can't seem to find pricing in euros, or if European institutions are even eligible to this Roy Meissner: Ask them, like we asked Atlassian for a discount/free license

Need to investigate export/import slack data options as well:

Rocket Chat (alternative that also supports self-hosting)

...

Hi @roymeissner, I didn't check fully and as I can't see which apps are currently our slack is using. But, Rocket Chat has been extremely popular in open source projects and in the industry. Heard about it from several noteworthy people so just a suggestion. It may be interesting to look at it in the decision process. It even provides hosted solution for 500 users at Euro 50/month

Features of Rocket Chat worth considering for a great open source chat software for

...

teams:

• Video conference built in
• File sharing
• Link preview
• Integration with GitHub, GitLab, Confluence and many others.
• Native apps for Windows, Linux, Mac
• Mobile Apps for Android, iOS

My personal opinion, if SlideWiki is opensourceopen source, then go for opensource open source team chat to reflect the opensource open source in true sense (own your chat messages then handing over to third party which might have other interests some day - better privacy). I think Rocket chat provides features that SlideWiki teams team needs.
