Sorry about the short wait -- we've had literally thousands of applications in the first day, and we are letting people on by groups of 100 (and that step size itself will increase).
Thanks. One of our design points in fact is that you can use the School from a tablet. We're still a bit concerned about Safari performance on the iPad, but we're on the case!
We welcome people who have written (or plan to write) Haskell tutorials and exercises to post them on the School of Haskell, if they find its features useful. By now you've probably seen the Active Haskell demo in the beta screencast video? https://haskell.fpcomplete.com/beta
We also welcome good organizers (like yourself perhaps?) to write tutorials that consist partly or entirely of links to other materials. The role of editors and organizers is sometimes undervalued, but not by us!
