When you login, Guild Delta displays changes ("deltas", in math terms) to the guild roster since the last time you logged in. Specifically, names of players who have joined the guild or are no longer in the guild. See below for tracking other kinds of changes.

I didn't like being unaware that people had left my (large) guild merely because I happened to not be online at the time they left. And I kept being surprised to find that people I knew had joined the guild when I was offline. So I wrote this simple tool to discover changes in the roster.

Guild Delta only updates its list when you login. After that, it becomes totally inactive. This means that even players who join/leave the guild while you are online will be listed the next time you login. This is by design.

There are a couple of versions available. The basic "name/rank" version only stores players who have joined or left the guild, and changes in the rank of existing members. The "extras" version additionally tracks changes to the public/officer notes of existing members. You only need to load one or the other, not both.

If a player joins/leaves and you are running the "extras" version, then their notes will be printed along with their name. This helps with the problem of "who was that guy who just left?" in very large guilds.

By default, text is printed to the combat log window so that it won't get lost in the flood of crap that shows up in the main chat window during login. You can use the /guilddelta command to change this.

NOTE 1: If you switch between basic and "extras", you may get a flood of data the first time you login. Likewise, if you are promoted to officer rank, any existing officer notes will all be printed out the next time you login.

NOTE 2: There is no way IN THE GAME to change which fields are tracked. (Sorry, no time or interest in writing a UI to control that.) However, the list of tracked fields is set at the top of the .lua file, with comments. It should be easy to customize if you wish.
