Can I load a Library from within a Helper?

[eluser]kimp[/eluser]
Hi,

I have a function which loads the email library then goes on to send an email.

Since I need the function to be available from a few places, I want to put it in a helper.

The code works fine when it's in a controller, but throws an error when I put it in a helper.

Should I be able to load a library from within a helper? What about when I'm extending a native helper (i.e. MY_email_helper)?

Thanks!
