I don't know if this has been asked or not, but could users that do not log in for... a year (i don't know if this is a resonable period or not), have their games automatically terminated (lost, if the other player is active, of drawn if the other player does not log in for some time also, like half a year, to prevent a wining only because he had the luck to stay on the site for one more day), even if there is no time control. It is kind of... ridiculous that some tournaments like this pandemonium (14. Fevereiro 2009, 14:46:59) will never end, just because a user has not logged in for more than 2 years (and probably never will again), I know there is another game between two active players, but I'm sure that something like this would reduce the number of tournaments and therefore the site burden (even if at the first one or two days it would have to calculate winners in many tournaments). Of course, that could be avoided by using a time control when setting up the tournament, but... it is not expected that a player is quitting the site.

I don't know if this is doable, especially the "draw" exception, but if there is already a "grey bar" for users that do not login for more than 30 days, it means that the site already checks when each user logged in for the last time (the fact that it shows in the profile page, does not necessarily means that the site uses that information, but the grey bar does)
