Maybe a boring subject but its very relevant.
When two chess players agree on a time limit of x days , each can use this x days for every move. When a chess player is online its not mandatory to make a move. offcourse not. Its a free world. Why are people complaining about that I am online but not making my move? Its my choice. Go to live chess!! play someone else!!

You are quite in order, although it could be irritating if the other player is waiting for you to move, knowing you are online, and his time online might be limited and, in his opinion, wasted.  Nevertheless you are still within the time limits of the game as agreed by you both, so you are right of course.

But when this is irritating because his time online is limited he could have told me. I would make my moves quicker to be helpfull. Moreover ,he should not agree on long time limits. And why is he or she waiting? There are thousands of other players he could play with 'waiting' for my move.
