...it's most likely because of 2 reasons.

1. You gave up your child.

Plain and simple, if you did that, that is why your journal is locked. These journals will most likely either be tranferred to another sub-forum in the guild or eventually deleted.

2. You didn't give up your child but have not been by to post in said journal.

We've warned you; via PM and in the thread. If you don't PM the mule and ask to have your journal unlocked or PM the mule within a month to determine your child's status; then your child/children will be taken away and your journal(s) closed.
