Pinboard, Anytime

Pin a note to the wall; whoever comes by next reads it — even if you logged out hours ago.

Voice chat and parties only work when everyone is online at the same time. On most SMP servers people aren't: time zones differ, schedules differ, someone always logs in to an empty server. This adds wall-mounted bulletin boards for exactly that gap — write a note by the iron farm saying "took 2 stacks, restocked Tuesday", and the next player who walks past sees it.

Two boards

Pinboard — per-block, like a chest. Each board you place is its own surface; put one in each base or farm room for local context.
Ender Pinboard — one shared board for the whole server. Every Ender Pinboard shows the same notes, wherever it's placed. Use it for announcements, trades, and event plans.

Features

Two-pane reader: note list on the left, full text on the right, with author and date
Login alerts — joining the server tells you how many unread Ender Pinboard notes await; opening the board clears the count
Attach my location — one checkbox stamps your coordinates and dimension onto a note ("diamonds here →")
A local board's front fills up visually as notes are added, and emits a comparator signal scaled to its note count
Boards mount flat on walls like signs: no collision, and they pop off if the wall is broken
Delete permissions are configurable — by default anyone can clean up a local board, while Ender Pinboard notes can only be removed by their author or an operator
Per-player note limit on the shared board keeps one person from flooding it

How to use

Craft a Pinboard — painting shape: 8 planks around 1 paper.
Place it on a wall and right-click to read or write notes.
For the server-wide board, combine a Pinboard with an Eye of Ender (shapeless) to get an Ender Pinboard.

Notes

Notes persist with the world: local boards store theirs in the block, the ender pool in world data.
Caps, lengths, delete permissions, and login alerts are configurable in <world>/serverconfig/pinboard_anytime-server.toml (synced to clients automatically).
Install on the server and on every client. No other mods required.

Free to use in any modpack. Source and issues: https://github.com/KURONAMI333/pinboard-anytime
