Making a text editor appear with text inside

[Dirtchamber]

Hey Lynne,

That's actually a really useful mod, and although I'll use it for other stuff, it doesn't do what I need in this instance. See, the thing is, I'm using the Ultimate Media Gallery, and it's in there that I'd like to spawn a text editor with text.

So: is there a manual way to do it? Like, perhaps I need to edit a PHP file or a template or something?

Any help appreciated,
Dan
