Well I have finally done it and updated my site to Drupal 4.7. The main reason is the same as everyone elses and that is the formapi slowed everyone down.
Not only do have everything updated, but a lot of my custom stuff I have been able to get rid of and use standard Drupal, or my new favorite module views.
I have been able to instead of using my taxonomy_fm module that I wrote, I now use the views module with a few bits of custom php to do the job.
When I get a bit of time I am going to post the code I use for the heading.
