I'd love to release this as an add-on, however, I don't know the correct way to write add-ons for xenForo. I don't understand listeners and hooks. I did my mod by editing the templates (and probably working way too hard to make it do what I wanted). I'd like to give my code to whomever would tweak it and package it in a standard add-on format. I don't want anything, except for others to be able to have this feature.
If you are interested, PM me.

My people are often out camping. They have the option of displaying a special pin showing their "current location" when on the road. This particular feature would only be beneficial to forums related to traveling.
Any pin style or color is possible - according to admin defined options.
