As above says would be good to see a message reminding you to change your items so many minutes before tourney begins

Possibly under your train or fight log where it shows you have broken an armour

I don't think something that specific is necessary, but perhaps a message notifying you tourney is about to begin would be beneficial.

or perhaps a message reminding you to sign up in the first place...

Shouldn't be too difficult to add something like this. I'll see what I can whip up.

Or have a brain that can remember to do this or use one of the seven billion alarm clock reminder apps for your phone or PC so Ender can do something more interesting with his time.

Or you could just not care about tournaments and live a happier life.
