Standard markup expression.

Ok, I will do--but two quick questions:

1.  Do you have a do the < > conditional?

2.  Is there some way to break out of a pagelist when you've reached
your limit? It's kind of inefficient to run through every page and
just reject everyone past 10. It's doable, but not ideal.

No problem. Wasn't what I was thinking at all...
