Shoutbox

Ok I need some advise on this peace of my script. I want to make a plugin manager for my script, as you might know I'm working on a last.fm script. The point is that there are a lot of different feeds available so I want to give people the choice what feeds they want.

But how should I organise this? I was thinking of the following:
[Directory]

- [Last.fm]
- - main files
- - [Plugins]
- - - [TopArtists]
- - - WndTopArtists.xml
- - - JsTopArtists.js
- - - [TopTracks]
- - - WndTopTracks.xml
- - - JsTopTracks.js

But the problem is that Messenger Plus! Live only grabs the Jscript files in the main directory. How can I make it so that it also grabs the Jscript files in my Plugins directory?

Thanks in advance!
