Events plugin

Hi

I’m searching for a good plugin to show events as posts.

The best option would be:
– Having a post with a timestamp in the future
– Deleting the posts when the timestamp is lower than today

The first problem can be done with the plugin “The Future is now!”

But for the second plugin, I haven’t found anything. “Auto delete posts” doesn’t work… Would this be difficult to write myself? I have a poor knowledge of php, but basically it should just comparing the post date with the current date. The post can be deleted when the current date > the post date (for a specific category). Could this be done in functions.php?
