When I was in year10,I was on my math class,I just searched a couple of math questions on Google and found this website,and then I download this app from App Store,this happened in the first half of 2016, and then occasionally,in 2017 ,I found that this app is not on App Store anymore and just felt very lucky that I had already downloaded.At first ,I used rarely and did not even register an account but just look at some of the posts .I frequently used this forum and registered an account when I was near my spech exam and I realized I should give myself a chance to communicate with others but not only staying quiet,then I officially start my journey of firstly using an online English forum.
