>>12158182>is there a way to be notified when someone has replied to my comment or post?At the bottom and top of the thread on the left hand side there's a checkbox that says auto. If you've got multiple tabs open then check that and you'll receive a notification in your tab (on chrome at least) when you have replies.
Alternatively you can use your android device to search for an app called "F-droid" and get an app called "Clover" which has a thread tracker.
>is there any way to find specific topics I'm looking forWhen you go into a board there's a catalog option. Always have that enabled. On the right hand side next to filter you'll see [search]. Topics may not always have your keywords in it.
>MUST I choose a file whenever I start a thread?Yes you have to. This is not optional. It is an IMAGEBOARD. If you want text only go to 2ch.
