We can tackle this on several fronts:

1. Feature-oriented videos to demonstrate tools. These videos would accompany the documentation. I found this quite helpful to learn Blender 3D.

2. A beginner walk-through of Inkscape's user interface

3. A teaser/commercial with screencaptures of some of our talented community of artists working on professional projects with Inkscape. 

4. Migration from Adobe Illustrator to Inkscape for graphics professionals

5. A short series of how-to videos demonstrating how to make some common graphics tasks like: 

-How to make elements like vines/flourishes

-How to use Inkscape for package design

-How to use Inkscape for labels, barcodes, and templates

-How to use Inkscape for product design

-Using Inkscape to make video caption templates

-Favourites, or most-asked-for tutorials on the forums.

-etc.

6. Tips and tricks to do things quickly in Inkscape. Some of these things aren't obvious, but highlighting features and how to use them to supercharge your graphics workflow is key especially for production artists.

I can do pretty much all of these, with the added bonus of using Blender 3D as my Open Source video production software of choice.

My only real limitation is time, but I'm happy to provide my graphics and materials to the team so others can help by filling in the gaps when they get time.
