Why do people do this? They write their Journal, and place the date for a future date. I understand giving a little time for more people to read them, but here's what you should know if you do post date your Journals:
Don't Post date your Journal too far ahead. Members can't read your Journal until that date arrives unless they feel like sifting through your Journal Calendar. Besides, alot of people rely on getting their Journals read by other members too, If too many members Post date their Journals for next year nobody elses Journal will make their way on the Daily Index.
