We made some changes to the cookies about a week or so ago to better sync them across all of our domains. Try this: go to the main forum page at http://forums.sailboatowners.com . Put your cursor over your username in the upper right, then select Log Out on the pop-down screen. Log back in from that same page using the little login tab at the very top of the screen. I would use that screen to login on your iPhone for a few visits. Let me know if that doesn't help.
