I've begun nosing around but not sure I understand how PmWiki triggers
it. I could perhaps link it to a login script, or any zap function
for that matter. But what would happen say if no one logged in for
several hours? It might either send out several hours worth of emails
(breaking my limit) or skip some. (Or I could dynamically rename all
the address files... Yuck. It might also mean my newsletter might

I like that, but I am more concerned about reliability in getting out
my mail. To be honest I don't have a good feel for how much traffic my
site is getting so don't know if this would work. Suppose I could put
a markup that does nothing but trigger the action right on the home
page... That ought to get more hits. But would that slow down the
site? Would the page halt the loading until all 100 emails were sent?
That could be slow. Or would it work independently. I guess I don't
understand this process very well.

I do have CPanel. It does have a user interface that is very simple
looking. The only thing I'm not sure how to do is fill in the line
that says: command to run. What do I put there? A link to the php
function? An html page that calls the php function? I dunno...
Something more complex? Is it really that hard?
Thanks for the advice and input. Still looking for a solution, one
way or the other. Any other thoughts, anyone? PmWiki could use a
nice newsletter management recipe.
