After reading through some reviews today, I tried to Add to Favorites one of the providers. The screen turned darker, and nothing else happened. I checked My Favorites and saw that the provider hadn't been added. So I tried to add another one that was reviewed today, and the same thing happened. Has this function been disabled recently? I vaguely recall using it just a few weeks ago without difficulty, and used it on many occasions before April of this year.

All three of the women I added were added. I don't know what to tell you but it worked for me. Maybe you're at your limit? I think TER limits the number of favorites to 150.  

Maybe it's because I'm using the TOR browser. Are you using a VPN?

I also use TOR on my PC, and tried to add a new favorite, and got the same results you did.

Another mystery revealed... and yes, I'm using a VPN. I tried TOR, but it was too sloooowww.

for some strange reason, whenever I open your posts, I never seem to get around to actually reading them.

I too have this problem when I'm with a beautiful woman... I know she's talking, but my mind has a hard time registering what.
