There have been so many plugins released over time, that I thought it was time to organize them a bit better. Thus I have been collecting the various plugins out of the posts in this part of the forum and put many of them here:
http://github.com/nickgammon/plugins
If I seem to have missed any important ones, or what is listed is not up-to-date, please let me know.
Individual plugins can be downloaded by clicking on their name in the main window, then when you see the plugin listed, RH-click on the "raw" button and then "save link as" (or whatever your browser says) to get a copy of the raw plugin source code.
eg.
http://github.com/nickgammon/plugins/raw/master/AFK_timer.xml
That link would give you the raw source of the master branch (ie. the current one) of the AFK_timer.xml plugin.
At some point, perhaps it would be a good idea to organize the plugins into folders for the MUDs they were designed for, as well as a "General" folder for non-specific plugins.
Also, how would you suggest storing "complex" plugins, such as those following my structured-plugin paradigm? Would they simply be zipped up and pushed to the repository? It seems like that would make it hard to see the plugin's change-history though... although I guess perhaps an author could host its source on GitHub themselves or something.
