Even if you are not new to OpenOffice.org, you will always have a question about how to do something. Worldlabel.com has a recent blog entry that contains a slew of links and a good breakdown of the sources of support, help, guidance and resources for OOo.
The blog is a good general resource, too with a regular focus on, and support for, the Open Clip Art Library. You can rarely have enough clip art for your use and your students use.
Of course, while you are looking at the links there, you will notice that Worldlabel offers labels, too. That they are a company doesn’t automatically diminish their contribution. Open source FOSS does not imply never spending money. Among other items, they provide no cost downloads of templates for OpenOffice.org.
It further proves that this FOSS thing…Some companies do get it.
