To avoid confusion over badge hits, which can escalate into wars, how about having a "combat log" which records all actions you take and receive from others. This could tell you:
Who you've targeted/who's targeted you
What you/they've done
What the consequences were for the receiving player (traps and production points lost)
And it would have an option to delete entries from the log.

here's the sort of thing I was thinking of:


Made in paint, so it's pretty rubbish, but I hope you get the idea

Id prefer combat log to be split into different tabs. Where one would be for NPC alerts, other for combat third for hack, fourth for planetary alerts and so on... When there are new unchecked alerts, there could be a flashing button on the tab telling us something is happening..

Now making the content of the tab neater is another story...

Oh definately need this.

I'd like to be able to see who I have hacked tonight, so that I don't get into a war over it.

This was only a rough idea. Should the actions auto-delete every 48 hours?
