I've created 2 contacts to test with assigning tasks. However I am unable to assign them tasks.

They are 'AR' and 'Dang' but when I try to assign a task to them it says 'No contacts' in the list. If I try to type their name it comes up with:
"The person's not yet your contact, plea...." (can;t see any more).

If you look at my history of feedback, I logged an issue where I wasn;t getting any confirmation signup email. I wonder if this is related...?
