Yes the deadlines come and go for many of the assigned projects, but I suppose we can't complain, people get busy.
UAE integration has been slowly and surely getting finished, but it was supposed to be done last june.
Many bounties get assigned and never finished, which sucks because that means we wait a year to find out nothing is finished. Some things get stuck in place that way...
Still, the bounty system is great because you can contribute to what you want, therefore the user bases needs get addressed this way.
