Believe me .. you're going to be surprised at how easy it is.
I used to use
dasBlog as my blogging engine and stuck with it through a misguided sense of loyalty to the Microsoft platform it was running on. I struggled for a couple of years and finally switched to WordPress out of sheer desperation: my blog was full of spam comments and it was so hard to change anything.
Since then I've been so impressed with WordPress that I now use it for everything I build, even non-blog sites like
this one (still unfinished)
Good luck .. and don't hesitate to ask if you need anything
