ESOGuildActivityAddon is a plugin for the game Elder Scrolls Online that quietly tracks when your guild members were last online and saves that information to a file on your computer. It's designed for guild leaders or officers who want to understand their guild's activity patterns over time, rather than just seeing who's online right now. The addon works by taking periodic snapshots of your guild roster. For each member, it records five things: the timestamp of the snapshot, the guild name, the player's account handle, how many seconds since they were last online (or zero if they're currently playing), and their rank within the guild. All of this gets written to a saved variables file in a format that can be read by parsing tools or converted into JSON for easier analysis. Guild managers would use this to answer questions like "are people still active or have they stopped playing?" or "is officer participation dropping off?" For example, if you run a trading guild and need to decide whether to remove inactive members to free up roster space, you'd have weeks or months of historical data to inform those decisions rather than guessing based on who happens to be online at the moment you check. The data file itself isn't meant to be read by humans directly. You'd feed it into a spreadsheet, database, or analytics tool to spot trends. The author is also building a companion tool that uploads this data into Google BigQuery for more serious analysis. One thing to note: the addon requires two supporting libraries (LibStub and LibAddonMenu-2.0) that you have to install separately. They don't come bundled with it, so you'll need to grab those first before it will work.
