I'm fixing the ?p= issue for converting to Das Blog by actually creating a custom version of Das Blog for my own use.  I've hooked into the Application_BeginRequest in the global.asax.cs but there is a small problem, everything is a custom hook.  I've tried to find every hook in my own blog that someone linked into but it won't be 100% ... ever.

That was the problem fixed.  The problem found is how Wordpress did posts using the online system.  It used new line characters and did a conversion to I'm assuming a <br/> tag.  By reading the source code, I found Das Blog has ContentFilter in the site.config.  Now I just need to figure out how to make it display properly with some regex.
