So I suppose I should get started with writing this.
What do I need to get started.. where do I get it..
Its for mushclient mainly too

MUSHclient forums
Lua documentation (my language of choice)

Start simple and build on it a little at a time. Make an alias that does something mundane, add a parameter to it, make it call a script function, etc.

Learn regular expressions, too. They're your friends.

Where on the lua page do i get stuff?
and whos around alot that has aim that wants to answer my every question I might have

When I got lua it said something like
To open this file, windows needs to know what program created it.. then I'm suppose to pick a program

Lua is built into MUSHclient. Nothing to download. This is the main reason I prefer it. It's compatible with WINE, too, so you don't have to worry about getting Python running or anything like that if you want to use Linux. It's also marginally faster because it's an integral part of the program and not an external engine.

To use Lua, you just need to enable scripting and select Lua as the default language. I'm not recommending you do this, however, unless you want to build your own code from the ground up. Ethelon's system would cease to function, as it uses VBScript only.
