I am completely unfamiliar with citadel or its supporting community, but was told by a long-time reader of this site that it had a long list of console goodies tucked under one title.
This I find to be very true, although I suspect that my cursory efforts to get it up and running didn’t really expose me to more than a fraction of its potential.
citadel offers e-mail, messaging, calendar and other software bundled as part of a groupware project that has evolved through the 1980s and 1990s. This much I deduced from the descriptions on the Debian and AUR pages. If it looks like BBS interfaces from those decades, it did to me too.
I never connected citadel to a live system, so the image you see above is just looped back into my own address running the daemon in Mint (my Arch builds didn’t work). I did that partly because I am a shy and timid creature , and I wanted a chance to explore without an information overload.
The downside of that being, as you can see above, there’s not much in the way of real data shown. I can navigate the “rooms” and “floors” of citadel and access a few of the features, but my safe little sandbox doesn’t do much in the way of real interaction.
I leave it to you to connect citadel and put it to real use; for what I see from elsewhere on the web, there are companies that use citadel or a variation thereof as a means of collaborating between developers in different geographic locations. So it may be that you use it already.
As a full-featured suite of tools all rooted in the console, I can only give a solid thumbs-up to citadel … even if my own experience was rather brief. 🙂
