Ask HN: Various resources database for a team

Hey,

so we're a team of 8 developers and we have an intersting problem - we're using Slack for team, communication, and it's great, but there's one catch, for now we can't afford paid subscription and Slack limits history of messages, so alot of stuff is gone after some time. So we've started to look for an easy solution to share various developer related stuff (links, scripts, files), with easy searchability and ofcourse - that it would not be gone after some time. We're using Jira/Confluence, but we could not find anything easy to use for that. So maybe you guys have some recommendations? Thanks!
