When you open a post, look at the grey bar with the date on the left side, then go all the way to the right side of the bar and you will see a lopsided red trianble with vertical line in it: that is the ALERT button. Hit it and a page will open to discribe the problem. For whatever reason, you can only send one alert every twenty minute (or some such nonsense) so if you see several posts in the same area let the moderaters know it in your alert. All the moderaters will get the alert and the first one on line will delete the offending posts.
