Is there a way to edit the content that gets sent for a password reminder email?

I'm trying to edit the lines:

You have requested a Password Reminder from .
to:
You have requested a password reminder from...

I've edited the resx file and changed the case for that item but it has no effect.

Also, we use the term Sign In but the message says: Please login using...

We'd prefer a more user friendly lable for Portal Website Address:

Is there a way to edit these?

BTW, we're using v3.1 but I don't see a template feature in the lastest release.

Thanks in advance.
