XtremeSpeeds is a general purpose tracker that has an assortment of current movies, UK/American tv shows, games, apps, and a large contingent of WWE and MMA fans. The home page contains a Shoutbox which is usually disabled during major sporting events. Download times vary from blazing fast to horribly slow depending on the uploader and seeders. Admittance is by invitation only.
Notes about XtremeSpeeds: This tracker has a very friendly membership that is always eager to help newbies. They love helping folks learn the basics of torrenting. You don't need a seedbox for this tracker and it's easy to build up/maintain a good ratio. I found this was a great place to start building myself up so I could get qualified for the higher level trackers. MMA and WWE fans may want to join as it seems the fights get posted pretty quickly.
