I just find out that if you don't find a family within two days you'll be open target. But since there is a war, no-one recruits. Will this war end in 2 days?

The thing about a war like this is there really aren't any people looking to target innocent people. If I were you I would just change your quote in your profile to 'Actively Seeking a Crew Invite'. I dont think any families are uninvolved with this war so it's probably wise to just wait this out... As for the war ending in 2 days? Looking at your profile I would say you'll get a crew invite before you lose your 'Minus 48' Status, not to worry.
