You can't tell whether you are on a fork if you are getting orphaned stakes (question marks). Those are normal. Usually, if you have a hard time staking, it means the network is strong. Someone with a big wallet probably opened it after a long time and started minting all the blocks for a few hours. The best way to tell whether something is wrong with the network is to look at your connections. The number will stabilize after one day. Make a note of how many you have. If those are stable, given a consistent network connection and open wallet, then there is likely no fork.

The StealthCoin network has been running smoothly for over a year now.
