Often when I use the "Host Table" feature, my table vanishes off the list of available tables before anyone joins it. Does this happen to others too? What is the cause? Is there a remedy?

@vandana I have not seen any of the games credited to me as a win where my opponent never returned after 14 days.

Does it affect my rating if my opponent abandons a game? Does it affect their rating? If either/both of these questions is yes, please explain the mechanism. Thanks.
