I have to agree with you. I think it should be Thread Etiquette that when an attraction is first brought into the conversation, it should be written out fully, then can be abbreviated. This is for the consideration of newer members, people who aren't familiar with the rides, and even for some of the veterants. I had to sit for a while to figure out what TSI meant. Sometimes people will abbreviate the full name, like WWTBAMPI, really stands for Who Wants to be a Millionaire: Play It. It could be easier if everyone just said "Millionaire."
Exactly. Who wants to memorize an everything, or constantly check some acronym list, just to understand some rumor? Thanks.
