Hi Omerta, you actually can't. Members may edit their own posts for 24 hours, but can't delete threads. This is explained in the forum rules
Post responsibly - These forums are very popular and very public. Be aware that what you post here will become part of the permanent archives and will therefore be available online for an indefinable period of time. Other web sites, including search engines, may link to what you wrote, making it easy for others to find. Moderators will NOT honor requests to delete, edit, or otherwise alter your posts or username. If it is important to you to keep certain details of your life private, do not share those details here.
