Just go to the iTunes store and search "The Worship Initiative"
We would love to give the charts for free, but they are not entirely ours to give. We charge a nominal fee in order to pay the legal copyright holders and process all the necessary paperwork that involves. We are developing printable files for each key of each song and we'll be adding these in the coming weeks.
No. However, we have a group plan feature that allows your entire team to have access to the site! It is customizable, depending on the size of your team. See the group plans here.
We have great tees (and other WI things) available at The WI Store.
That would be great. Please do. Thanks!
