Absolutely, please help yourselves!
Also, the lovely people at CartONG did some translations into French, which they will be uploading to the drive soon, so look out for that...
The resources and workflows have been developed by the British Red Cross mapping team and a number of the HOTties who support the Missing Maps in London (to give credit where it's due).

Wow, great resources.
I was looking for something like these for a mapping party recently.
Thank you, thank you, thank you for sharing them!
Would you mind if we put a few in the wiki or on LearnOSM with reference
back to the source?
cheers,
