Some years back doenetwork changed from a .us site to a .org site.
If you run across any of the old doenetwork links posted here containing a .us in the link all you have to do is change the .us to a .org and the link will work again.

We will 'clean' these up as older threads get new activity.
If you happen to find a thread with the older .us links please copy the link to the thread and send it to one of the mod's here for the UID forum and we will be happy to get it corrected in the thread.

thank you!
