@Lindagaf Banner is the system students use to register for classes. This semester when registering for classes, it worked for the first few minutes and then crashed for like 20 minutes or so due to the number of students trying to register at once. It was frustrating experience for members of the freshman (incoming sophomore class) and they could do much to improve it by getting more sever space. Next year, I am a residence assistant and I am advising my freshmen to bring ethernet cords, because the wired connection was apparently less buggy.
Although I gotta say, two of my favorite classes I have taken and have had the most impact on me are two I am taking this semester because I did not get into my first choice classes during registration. It also happens to coincide with the two professors that happen to have taken our class out for lunch haha.
