It looks like you have been a member for quite sometime so you really are aware that some folks upload skins at times in bunches and then have a dry spell, for lack of a better phrase.
If you have some favorite skinners you can just go thier personal pages and see what new skins they have uploaded.
Another thing to remember is it takes lots of practice making skins before the skinner developes the talent and skills that help them improve. Take a look at some of the very early skins of the folks you now like, bet you see that they improved.
I even bet you that what you now think of as quality is probably different from when you started downloading.
Give folks a chance, they may turn into tomorrows Master Skinners.
