Ahh, take this idea and use the HttpVariables recipe
and you can do the same thing on onepage!  Simply pass
the start and end arguments as url (GET) variables.  

To reference the first one hundred lines:

[[(Signups)Pager?Start=1&End=100]]

And on SignupsPager you put:

(:include Signups lines={$!Start}..{$!End}:)


The hard part now becomes creating the proper links
for the previous and next pages!  (Again, another use
for a math recipe)  But this would also be hard if you
had Signups1, Signups2...  At least now you can do all
the logic on one page.  Here is some sample logic:

(:if equal {$!Start} 1:)
[[Next -> SignupsPager?Start=101&End=200]]
(:if equal {$!Start} 2:)
[[Next -> SignupsPager?Start=201&End=300]]
...
(:if:)

Use similar logic for prev.  The really hard part is
knowing how long the page is to know at what number to
stop at!
