FYI You don't have to delete and repost (for a typo or mistake in your post's titles) when it is still editable.
There's a 10 minutes window for that purpose.
You can edit the title by clicking the blue pencil icon on the left side of the title, in a post.
Not sure if it's a bug or me just being dumb, but I only see the edit option for text posts, not titles for links to images.
Well, if it's a bug, it's a nasty one because no one else reported it.
Once you posted, just refresh the /all/new page and if the title isn't what you wanted it to be, click it, it'll lead you to the post page and you'll be able to change it (in a 10 min time window)
I did some testing and confirmed the problem is me being blind.
Thanks for pointing this out, it will help me in the future.
