I've been trying to install the unsupported EggAvatar addon, and though the user options for most of it appear in my admin panel, the user group permissions do not. I suspect what's why nothing is showing up on the front-end. I thought I'd be able to go into the database and set the user group permissions manually, but couldn't figure out how the tables worked or my plug-in's addon_id. (I looked in the XML file, but the only addon_id field is the name of the plug-in itself, not the random-looking string of letters and numbers in the tables.) Could anyone point me towards resources on how to understand the user group permissions tables, or how to figure out what my plug-in's ID would be?
