My sister's suggestion, she thought it would be good as i wouldnt have to change my initials :) but id kinda choosen the name 'Alice' at that time (probably because it felt like i was falling down a rabbit hole hehe).
Since returning to the forum, i decided to go with the name she mentioned. The 'Dee' was just random though lol, i thought it sounded nice :) + there were tons of other Rachels so i had to pick something to make it different lol.
