Have there been problems taking classes through the Internet?

The students get used to the virtual classroom very quickly so the interface is not a difficulty.
Just as a physical school has problems with rain and snow, a virtual school has problems with connections. The most crowded and popular ISP's, AOL is the most notable, have had the greatest amount of problems when a server gets crowded and the bandwidth has to be allocated among many users. These problems will disappear when we all have DSL and cable modems. Until then, it is important to have a dependable ISP, good connection and as much bandwidth as possible.
Otherwise, there have been no large or recurring difficulties.
