All your games so far have a 3 day per move time control. If somebody drops a piece, it could still take more than a month to get to a mate.
There are many legitimate reasons to allow resignation. That is why it it an option in every over the board tournament.
Please give at least one legitimate reason it shouldn't be allowed.
I'm basically polling various sites. Another site upgraded recently and doesn't have a resign button as of yesterday. I told the owner it makes the site unique. I am not saying it's better just different.
The competing site now has an uncolored resign button. I have suggested it be red with black letters.
Pretty snazzy imo
