It's a cracking little tool for text editing, and I have created a somewhat useful language that should pick up most of the basic code things for wagic - the way that wagic is coded means some of these will still be coloured in "text=" lines but that's not too bad.
To install to Windows 7 -
Download the program and the file from mediafire.
Chuck the file into "C:\Users\"username"\AppData\Roaming\Notepad++"
When notepad++ is open - press languages, and it should appear at the bottom of the list as "wagic".
Other operating systems should follow a similar step, only the location of Notepad++ could be different - I think on XP it would be "documents+settings\"username"\appdata\Notepad++
If you have already gotten other user languages installed, you'll need to merge the two XML files.
