Create Multiple Posts for RSS Output

Hi, Ive just had a thorough search through your database for an hour and can’t see anything remotely similar to what i’m trying to achieve.

Ok ive just signed up with WordPress and im running the latest version. What im trying to do is produce a post for each of my daily competitions (60+ per day)and then use the rss output elsewhere. I’m setting the posting times to being roughly about 3 hours before the start of each competition and setting my rss output to about the last 10 posts and then using Yahoo pipes to sort the posts so as the oldest ones are at the top. This in itself is giving me probs but i wont mention that the now.

My main problem is that for the next days competitions i have to go back and edit every single one of the previous days posts and change the posting date and time as 24hrs down the line. Can you think of a better way of doing this. The posts in themelves aint really that important as it’s more to do with the rss feed and utilising the time delay of the posting.

All help appreciated and i’m sorry if this is discussed somewhere. Thanks
