Getting started with liferay portal and mysql

I searched a little while when looking for how to get started with liferay and store my data in a mysql DB.
There are some hints in this documentation(I'm using a tomcat bundle, version 5.1RC).
But it's actually simpler. I didn't even need to explicitly install the mysql driver by hand.
Just change

conf/Catalina/localhost/ROOT.xml

There, enable and adjust the lines for the mysql driver, disable the hsql stuff.
At first start, the database is created automatically.

Another thing I searched for a while is the password you need for the first login - the default admin account...

The user/password combination here is test@liferay.com/test - can also be found here.

Let's see what liferay brings... I'm interested in and excited about using it to couple together all the data services I need in my daily life - wiki for unstructured information, a blog for you to read, addresses, calendaring, todo management, project timetracking and stuff like that.
I'm evaluating liferay for that sake - it seems to bring quite some portlets in these areas, and I'll add the missing ones
The other thing that seems interesting in this area is the exo webOS - part of the exoplatform portlet container. What I dislike always when looking at exo is the parallel offering of multiple different distibutions packages, but that seem to become normal when looking at todays software platforms - feature-rich ans large, they are.
On the other hand, I will probably be better of making my way through that complexity, than wirting every app I need on my own...
