@Sohee_30 Well, you can pick two options. Sign in or as a guest though I would recommend signing in (you might need to wait for the invitation email though)
Signing in can give you this benefits: Commenting, book marking, subscription, etc..
Book marking mark where you read though it won't update you where you read it
While 'subscribe' will tell you if the story have updated.
If you want to search a specific story, tap on search. It contains 4 categories: Work Searcg, People Search, Tags Search and Bookmarks search.
Though I highly recommend Work Search because it's more easier.
You can just type any author names available (there's a lot) and also pick a language, ratings, fandoms, and more.
Then we have the tags. This one is a bit complicated if you aren't used to it.
Firstly, if you have a specific ship you want to read, you can select 'Relationships' and type, [Insert name]/[Insert name]
If you want a specific character, select 'Character' and write it (They'll will give you option to which one you want)
Now the best one, 'Additional Tags'. Have tags such as 'Comfort' or 'Angst' or just anything
Oh and you can also select categories for the ships. If you tick the box.
F/F= Girl X Girl
M/M= Boy X Boy
F/M= Girl X Boy
Gen= No romantic relationship
Multi= more than one relationship/ poly
Other: Other relationship (I have no idea what this means)
(+Invitation Email can take minutes, hours, Days and even weeks so please be patient)
Any questions?
