Good morning... my first post using WP!
The template obviously is the first thing that needs to be tweaked. I really don't like side bars in blogs, so I've been looking this morning at various templates that take the sidebar out and add in a menu at the top. I'm actually still a little bit confused on how this is done, but I don't think it's all the difficult, I just need to work it out.
There are definitely things that I'm excited about with this system. I like the idea that if I do some neat tweak, I can wrap it up and a bunch of other WP users might benefit from it. I like the ability to add Pages as well - this makes WP into a content management system of sorts - beyond just for blogging. On my custom blog, I had some basic photo album and video features as well - I'll have to see if I can work out adding that stuff in, or seeing if there's a plug in.
Helge in my comments recommended the RunPHP Plugin which allows you to just add PHP into your blog. This combined with Pages makes the whole system *very* powerful. I probably want to figure out how to add things in a more traditional page approach first, but that adds great hackabillity and really shows the difference between PHP and Java.
Okay. Prepare to hear more about this soon... :-)
