Not sure what you mean.
The photoshop exchange is still available if that's what your asking.
It does seem to take an awful long time to get things approved though.
yes! but more upload since December 2011
what is the reason
I don't know, since it's been years since i uploaded anything to the photoshop exchange, but there appears to be more recent uploads
for pixel bender:
Maybe people are using the photoshop marketplace instead
I do not think it is strange that the last load is arrested in December 2011 thank you for the links,
