If you have written and tested a plugin, and you're now ready to share it with others, congratulations! Glue makes this process very easy. Glue supports exporting a plugin (which may be just one file or multiple files) as a single file with the .plug extension. .plug files can be shared directly with other developers or uploaded on GlueVault.com.
To create a .plug file:
Open Glue
Select "Plugins"->"Create Plugin"
Press the "..." button to find the folder that contains your plugin
Select the folder inside Glue's Plugins folder that contains your plugin. If you are using Windows 7, this may be located in "c:/Program Files (x86)/FlatRedBall/FRBDK/Xna 4 Tools/Plugins"
Click OK
Select the location and file name for the exported plugin and click OK
You will now have a .plug file which you can share with others or upload to GlueVault.
