I'm really eager to start contributing HITs to the daily thread but I'm worried about reposting. So I have a couple of related questions: 1. Are reposts allowed? If yes, under what circumstances? 2. Is there a good way to search the daily thread to see if a HIT has already been posted? Usually by the time I get to them there are already half a dozen or more pages and I don't have the time to wade through all of them. Sorry if these are dumb questions or have already been answered elsewhere! I did a quick search and didn't see any existing information.
