I've been reading like that too it's quicker and u don't skip any updates.
I've bookmarked webtoon_update and yaoi_update and sign_in page in chrome so its easier. I rate for the mangas that i mostly miss so when it updates it notifies me(but the notifications take some lag)
Just me blabbling...... Its embarrassing ⁄(⁄ ⁄·⁄ω⁄·⁄ ⁄)⁄
It's been 2 years or more(using mggo) and i never rated any mangas, tagging 'em, commenting, the grouping as reading want to read and already read Nothing(too bothersome)...... Recently i saw a someone's page like they read every manga in this site...... I got envious jealous and mad(feeling stupid) So i've started rating mangas(so far 10 percent) (⌒▽⌒)
Being honest It's hard & really tiresome and i really wanna mark every manga ive read
if you dont want to wait for the update notice, click yoyr history and you can browse your previously read mangas, it tells you if it has been updated since your last read!
