Many members have asked for a way to upload photos to the critique forum, without having to upload them to curation. You can now upload photos in the ordinary fashion and then select which photos you want to submit for critique or send to curation.
To submit a photo to the critique forum. Simply enter the cog wheel menu on the photo and select "post for critique".
To submit a photo for curation, you can select "submit to the curators" either in the cog wheel menu or on the "photo details" page.
