First off I'm not very literate in security issues or computer terminology so I'm sure I am going to come off as a complete moron but can anyone tell me what the security risks are if someone has my IP address. Can they access my computer? Can they access my internet based e-mail? Can they find out who I am? If I access a forum through a link from my internet e-mail can the administrator of the forum (or anyone else) Hack my internet e-mail? Hack my computer? Find out who I am? I have a Powerbook G4 and I'm running 10.4.11 Thank You!
