Personally I find it kickass that YNK finally got into the 21st century and turfed that phpBB garbage.
Now THIS board is much more like it. I know it is different and YNK still has some account synchronization problems to work out, but it is a far more robust and secure messaging board by far.
If you haven't had the chance yet, go check out some of the settings and new functions you have to fart around with. You just might be surprised at some of the power you have available to you...
