I've been looking at options for hosting a forum for our products. Somewhere a little less formal than just a support portal, but with content available to the general public for future reference. Discourse is my preferred option, but unfortunately we can't really afford the USD$100/month yet to get an instance of that.
So I put together a subreddit instead - check it out here: https://reddit.com/r/Signata
I'll post more informal updates there - this blog will of course have our product announcements, but any sort of in-progress features I'll throw over there to test the waters too.
