Great. I've just watched one as I'm mobile, but they look well done!
It just goes to show that you do not need to be a developer, or know alot about computers to help out with OpenLP. In fact almost any skill set can be put to good use.
OpenLP needs people who can:
Speak other languages to offer support on the forums and the support tracker.
Speak other languages to translate OpenLP.
People to help write the manuals and document features.
Work with media, to produce how to videos.
Test OpenLP and produce concise but detailed bug reports.
Promote OpenLP, if its with in your church, denomination, or if you have express with P.R. on a wider scale.
And last but not least developers to fix bugs and to develop new features.
If your skills aren't on the list, doesn't mean you cant help. Just contact the team, and I'm sure they could find something for you to help with!
