Over the years I used Twitter only for job-related functions, specifically for extended school field trips. To avoid confusion for the parents, I created a new account(?) every year.....#specialtrip2013, #specialtrip2014, etc. Now, I'd like to delete every one of those old accounts(?) and establish a new Twitter account. I use scare quotes for "account," because I don't understand whether these are "accounts" or just different variations of my overall account.....in searching for "how to delete my Twitter account," I'm concerned that I may not be deleting what I should, and it could lead to problems later on. Any help appreciated!
