Force tiddler to appear at the bottom of table of contents

[kash....@gmail.com]

At the moment I have a tiddler that I want to keep at the top of my table of contents, with the rest in alphabetical order, so I just prefix its title with "~".

I have another tiddler that I want to keep at the bottom, but there doesn't seem to be an appropriate character to do this. Is there another option besides prefixing it with "Z"?

Thanks for your help!
