For more attraction-specific websites, try both doombuggies.com (Haunted Mansion/Phantom Manor) and tellnotales.com (Pirates of the Caribbean). Both have message boards as well.
I like Allearsnet.com and mousesavers.com (she basically releases any type of special concerning Disney, but has great money saving tips, too.......you can sign up for her newsletter and also for a list of special codes that Disney releases for hotels, etc...), and then I listen to live365.com, specifically mouseworldradio!
WDW Magic is good for rumors, and the unofficial rules are no monorail/harry potter/ Indiana Jones from DLR at MGM/ 5 th gate threads, unless you hear something groundbraking to that rumor, they all get discussed the same way as the 50+ threads on te same topic before them....
