Private remotes arrive without a websocket
You can now send private one-to-one and group messages, and watch each one go from staged to pushed to pulled. The whole inbox docks at the corner of every page, and nothing needs a websocket.
Also leadingTook the lead from Timezones join the conversation #155. People can now send private one-to-one and group messages, watch each message move from staged to pushed to pulled, and keep the inbox open on every page.

You open /remotes, click a handle, and type. Your message shows up before the server answers, wearing a dashed circle marked staged. A moment later the circle fills in as pushed, and when the other person reads it, a second dot joins it. It is marked pulled, with the time. Above the list are a search box and two tabs, Open and Stashed, and a docked copy of the whole inbox can follow you around the rest of the site.
Credit goes to xHeaven, who built remotes. They include one-to-one threads plus orgs, group conversations capped at 15 people, where the creator is a maintainer and everyone added is a contributor. No websocket in sight. An open thread asks the server for messages after the last one it has every 1.5 seconds while there is activity, every 4 seconds once it has been quiet for a minute, and not at all in a hidden tab. Threads load 50 messages at a time, inboxes 30 conversations at a time, messages run to 2,000 characters, and sends are capped at 30 a minute.
There is one catch if you are hoping strangers will find you. Requests are built but switched off. Two server settings, REMOTES_REQUESTS and REMOTES_EVERYONE, both default to false. The first would let a stranger send one held message, and the second would let you accept remotes from anyone. Until someone flips them, only people you follow can start a remote with you, the Fetched tab stays hidden, and a stranger's first message is refused.
