 AJAX Message of Interest (MoI)
This system is designed to make communication much easier in D&D Wiki. More to come.
To use this new system, all that you need to do is press "MoI a user about this change" in the edit bar before saving a page. You can then select which part of the page you want to MoI, and which user you want to MoI.
For example, if you are editing a discussion page such as the following:
== Balanced? == Hey, I want to know what everybody thinks about how balanced this is. --~~~~
Then you would enter the following in the form.
If any problems arise, do not hesitate to contact Blue Dragon.
