As the instructions to installing a new payment module in Virtuemart for Joomla! I've done this video showing how I apply it to my demo site.

Introduction

Well I thought I'd write about it as it is my very first ever Joomla module.  Not just the fact that it's my very first but also because of the surprising popularity.  It has been featured as a "New & Noteworthy" extension on the front page of the Joomla.org Extensions website for about a week now.  There have been several positive reviews but more astonishingly over 1,000 downloads in 10 days!  May not be much to some people but for my first Joomla extension, I've been quite impressed.

This module doesn't really need more documentation as it was created for fun for a friend.  To be quite honest,

1. you could get the generated code that revolvermaps.com give you,
2. go into your Joomla admin panel,
3. create a custom module,
4. make sure you click on "Source" (so that it isn't in WYSIWYG mode) and
5. paste the code.  

This extension just does all that for you in its install and you just play with the parameters.

I felt that if I make this an article, then anonymous users can leave a comment.  If you are a registered Joomla.org user, you can go to "http://extensions.joomla.org/extensions/site-management/visitor-maps/13254" and leave official reviews and comments there as well.
