G'day chaps.

First off, excellent service. I'm really liking the power of RTM. It tells me what I need to do in my life :)

I was trying to start using the tags, which seem a perfect way for me to associate various tasks with the course they're for (I'm a student).

But - I can't create any! I go to Settings->Tags but see no option to add a new tag. the dropdown gives me options to delete and merge tags. I can't see anything there or anywhere else that might let me add a new tag.

Clearly I'm missing something - anyone tell me what it is? How do you normally create new tags?

Thanks!
