Daryl,

it's probably something to do with the browser that you use to access
the newsgroups. If a poster does not expand on his heading for the
thread and use the message body, then some browsers do not allow you
to respond to it.

Hope this helps.

Jackson -

I can't reply to your posting directly - I suspect the "^" character in your
posting subject may be the culprit.

To answer your question, the carat represents a 'to the power of' operation.
*That is x^2 means x squared (x times itself). * y^3 means y cubed (y times y
times y).

Hope that helps!
