Saw the impressive new website at Mostphotos, looks very professional.    Also got an email from the CEO with an invitation to join.  Good stuff I think.  Had a couple of concerns with the licensing/ related info and terms of use as presented on the site and was promptly thanked by Lina from their office, for bringing to attention and assuring the matter was being addressed immediately.  If they do that I think I'm all set for joining the Contributor rank on this site esp. since they also act as storehouse letting you download your content free in case you lose it somehow.  Next comes the sales part.. maybe its a trickier one but one will have to wait and see.

I got invited too and thanked them politely but no thanks. I dont have time to waste on another none seller. I am sticking with GL because it seems they are a fair agency, but I only had 1 sale in 4 months. I do not wish to add any more of those agencies.

To each one of us our own I guess As for me I had bad experience on GL because they rejected an extraordinary number of my files for reasons not clear - since those images were accepted at various other agencies (I'm on 10 stock sites) - so I stopped uploading to GL. 

With Mostphotos my initial contact has been a positive one and the new site looks Great so i plan to give it a shot there
