I am user of this site for more 2 years.even though it is one among the faster email services available, technically the design of the site is not on a very strong foundation, I personnaly fell.whole site is developed using frames which means windows inside windows that change dynamically in a frame depending on the options you choose in another frame.problem with this site is all the frames are not loaded at once.if leaft one is loaded right one is not, if right one is loaded left one is not loaded etc., each time the user has to refresh the respective frame to load it, something not very comfortable.otherwise in terms of features and speed this undoubtedly is a good service.
