According to patch notes
"In our next release we will give users the option to remove it completely in preferences."
When will your next release be? I'd like you to know that I won't be using the Plays.TV client while the watermark is present. I upload videos not just to Plays.TV but also to YouTube and do not want any lame watermarks. This is almost as bad as the 360p videos you see with a watermark of Fraps or Bandicam.
P.S. Your SSL certificate is for the wrong website, please fix. Luckily, my password is auto generated and I don't use it anywhere else, but otherwise I'd avoid logging in.
Thanks for the feedback. This blog post should explain everything and the changes we'll be making: http://blog.plays.tv/watermark-update/
We're also looking into the SSL certificate issue you mentioned.
