How to add a manga in my Collection???

Who knows how to add your fav. manga in my collection.Help please

Find the manga, then click on the add to favorites, then click replace.

Can i only store 10 fav. mangas??

I think we mixed two different Functions here:

Add to my Favorites <-- EX_Soldier already explained how it works.
Add to my Collection <-- Not functionally as far as i know

You can add up to 10 Fav. to your List.

I haven't set it up yet, I am trying to figure out how to make is significantly different from just adding it to your favorites.

yeah the collection thing i don't think is being used a whole bunch. >.<
