ParisEye,
As you may see in other SV threads, the site has been quite slow in sales, but then they may be just building a large portfolio before real marketing begins.
I have sent them an email about a problem I have with keywords (only the first keyword is read from my IPTC data). A few days later they asked me to send a file to them (by email). Weeks later I got an email saying the problem is not forgotten. Meanwhile I ceased uploading (I have maybe 25 images there).
Regards,
Adelaide
