Twice today, I've put out a seek for a new game for turn based play, then left the site. When I come back, my seeks are gone.

Me too... Sent seek, not accepted

I tried a third one just after starting this thread, and that one got accepted, so I got a game started. I just don't know what happened to the first two. They were on my open invites list when I left the site, but they were gone when I came back.

When you complain to the staff, you don't give evidence of it working! 

I've worked tech support enough to know that the more detail you have to work with, the more likely you are to find the problem.

Maybe the database admin needed to rollback the seek database.

I've noticed when I leave the site it cancels the open seek. This is probably to reduce the number of people left hanging upon accepting a seek.

When the time control is 3 days per move, they'd better get used to waiting. I certainly hope this isn't intentional. If I put out a seek, I don't want to have to sit around for an hour waiting for someone to accept it.

I have the same problem. I've put out a seek for a 960 game, random opponent, and after a while the seek disappears. I tried a couple of times more, and the game proposals dissapeared again.

I am also having this problem.  The seek disappears within less than a minute.  I didn't log out...didn't leave the site...just kept hitting F5.  All of a sudden [poof] seek is gone. In case it matters, this is for a 960 game.  This happens to me often.

Something in my blog might help (such as trying a different browser or clearing your cache, etc), maybe possibly perhaps...if not and the problem persists contact the staff directly via Help & Support at the bottom of the page

My open seeks keep disappearing

Me too, and at the same time my current game list keeps growing

Something's definitely wrong.

They should be under http://www.chess.com/echess/myhome.

When there is one it will be under the heading "My Open Invites".
