New User First Login Experience Selected

On my first day here I set up my new IdeaScale account! When I went to create my account, I noticed that all new users have to designate what time zone they sit in, The drop-down box to select your time zone features many, many cities to choose from. It'd be a smoother first time login experience if the various cities were grouped into more generalized time-zone clusters. For example, there were many EST cities to choose from. This is a small thing, and I don't know if we're tracking user location for any specific purpose, but I figured any improvement to a user's very first experience with the platform is worth considering. Still learning the ropes here, this is my first idea submission!
