Hi Colin
The guys are working through making sure that all the Joomla Sections and Catgories exactly match your site map and that all of the menu options lead to the items detailed on the Site Map.
Dont worry about the missing "How to Guide List" on the front page, they are in the process or repairing the, we were having numerous problems with cross browser support and the rollovers that you wanted. Should be back in the next day or so.
Once the categories match all the sitemap, I think we should lock this down and you can start entering data.
This should be completed by the end of today (Indian work day)
Also
Thanks
Mike
