So I made this door: https://github.com/hmderdoc/CalenDoor/releases

I'm sure in some regards it's quite obvious what this is and does; what might not be obvious is why I wanted to make this, but here's a hint it has to do with the telnet gateway portion.

The utopian vision is I didn't just make this so people have a calendar app, although it works for that, the vision is that by creating shared calendars there's a way to drive users to a specific place at a certain time, if you create a calendar event with "telnet://somebbs.net" as a location at 11PM on Friday, and you open CalenDoor you will be able to just hit a key to connect to somebbs.net when the event comes along.

The problem I'm trying to solve is fragmentation and general BBS lifelessness. Sometimes I hear about time-boxed BBS related events such as chat meetups, testing sessions, demos, game parties, etc from many sources, irc, discord, mrc, forums, word of mouth etc. but I am sure there are just as many I don't hear about or I hear about them and forget about it. In some ways this door is also designed with a first time BBS user in mind - it sort of sets expectation about when and where to expect activity rather than walking into a ghost town. I might put it in my logon sequence personally as I think a filled calendar would certainly make the BBS world look more alive.

The main things preventing my utopian vision would mainly be around how to aggregate and manage events. Right now I'm bundling a shared calendar "BBS Events" and that might work provided someone could act as good steward, reach out if you are interested in helping manage a calendar or have any ideas for calendar management. I certainly could build some API + form thing for scheduling intake on that calendar but that feels like a separate project from the door.

I tried not to get too crazy with this app with my personal flair and just treat it like a utility without a lot of fluff - it's at v 0.1.0, give it a try, if it doesn't do something you want, LMK, maybe it can be changed.

This is a cool idea. I feel like there should be, in addition to current features, and if this isn't already in there, a way for the door to serve its
calendars, and so a big group of BBSes could all point to one or a few particular BBSes, and all have the same calendar.. perhaps with some way for BBS users
to add events, but that might need some kind of approval process or something.
