>I would love to... it's it as easy as writing an article and sending it to an editor?

Almost. You should contact the editors and tell them you would like
to write for them. They'll likely send you an author kit a template
etc. They'll also want to know what you want to write about <s>,
before you actually do any writing... It's not a difficult process
if you have material to write about!

If you write for a general purpose magazine it's different than
for FoxPro Advisor etc - you need to try to keep your
topic more generic and use VFP code to make the point...

I can't overemphasize this - seeing things done with VFP is much
more important for non-VFP programmers than MS *not* marketing
VFP. If people see VFP crop up occasionally when they open up a
developer magazine and see that a) it can be done in VFP and
b) be done much more efficiently in VFP some people are bound
to notice.
