I've deleted teams on my phone via the Team Manager, yet they still show up on the iscorecentral website. Is there any way to delete the teams on the website?

If you Export your database, they will be removed from the website as well. The website is really just a "copy" of your device. Any time you Export, it overwrites what is on the website with the data from your device. When you Import into iScore, it is replacing what is on your device with what is on the website.
