#1144 is fixed and I believe I marked it so yesterday (it was fixed a bit earlier but I forgot to mark it in bugtracker)
#1172 has been bounced back to Peter Marklund for either some explanation or a fix depending on what he wants to do. The code's a bit convoluted, apparently because it is used elsewhere, not just by the add-one-user code, and I figured he could tell me what's going on much more efficiently than I can try to figure out what's going on in that code. The bug's obvious, what's not obvious is how to fix it without breaking other chunks of code that call upon it.
I think Dirk was going to revisit the calendar problem, which he thought was fixed.
