I have been an OpenOffice.org fan since 2000. It has been better and worse as a product at different times in its history. There are forums in which I have participated and spewed as much knowledge as I can to other members. I have been somewhat of an OOo evangelist and have given presentations at different meetings (Linux enthusiast groups and corporate groups) as to why people should seriously consider OOo.
I started reading a blog a few months back that has helped me with some of the more detailed uses of OOo. Though I certainly don’t have as much heavy daily use for OOo as some people, I have enjoyed reading Solveig Haugland’s OpenOffice.org Training blog. She has some very detailed how-to articles at the site as well as some great articles on how to make the transition to OOo.
If you see an article that does not apply to you at the time, just skim over it and know that it is there. You might be surprised by how often you find yourself going back to the site to check out a how-to that you previously skimmed over. Solveig has a great way of simplifying a complex process.
There is a lot of good stuff in her archives. Be sure to search around for tutorials. I used to hit the forums when I needed help. Now, before I go to the forums, I check out Solveig’s site.
