ILuvParis: I'd like to point out another possibility. Your browser may be set up to use a caching proxy server of some type which sits between your computer and the outside Internet and stores recently accessed pages in an attempt to reduce the amount of traffic to the outside world. (Did that make any sense?) Anyways, because of this caching server, you may not be able to see recently updated webpages until a few hours later. Your system administrator/Internet service provider may have a solution.
