Slowly we're making progress, the feeling is good and we've decided to go 'live' with the drupal based corporate site. So, http://themodularcompany.com/ is now the official homepage.
Catchall (our not-yet-developed domain parking lot) has been moved completely over to drupal now and Joyce has done some really neat stuff with it for http://softwaremagazines.com/, and in the next couple of weeks she will work on getting more of the domains developed.
I've learned a bit more about modules and have finally figured out what is the proper way to add a bit of javascript to the end of each page, it is done using a callback hook called 'hook_footer', any code you return from there will be added to the end of the page that you have produced, just before the /body tag. So, it was a lot simpler than what I had done so far and the best bit is that it no longer requires a block to place the javascript in, something that could be easily overlooked.
I've spent some time trying to get the city datatype to work properly in autotagger.com, but without much success, the possibility to wipe the images attached to a city remains. A guy called 'Crell' on the drupal forum has given me some hints about how to deal with this and I'll be trying his method shortly.
There is still plenty of stuff that needs to be figured out but for the most part the feeling is good and I think drupal is here to stay, it would have to be a major disappointment somewhere to make me switch it off again. And Joyce isn't going to let go of drupal unless I bring a crowbar or something like that :)
