I just had a quick question about "custom watermarks." I notice that the "Interested in having your own custom watermark? A+ membership coming soon..." message is still showing up when I go to edit my settings--out of curiosity, might this service be available sometime soon? :-)
This is near the top of our development list and we hope to have a beta of a new image uploader available in the next few days. We will likely open the beta up to all A+ members initially and then the full community soon after.
There is a new watermark tool which will allow A+ members much more control over their watermark design (select font, text style, size, placement and text).
Custom watermarks are already implemented for A+ members. It is possible to use custom text plus a variety of different fonts, colors and sizes. You can set the watermark on the image upload page under the watermark tab.
