Effective immediately, special apps will be limited to 3 per account per year. There is still a 30-day waiting period between special apps. Applications will count toward this limit regardless of whether they are approved or denied.
As I posted in another thread (http://www.zalanthas.org/gdb/index.php/topic,33596.msg412036.html#msg412036), 90% of players who special app will find this change does not affect them at all.
