[Low Priority] Being able to edit bulletins

I saw that no one has suggested this, so here I come. Doesn't it bother you that you typed three paragraphs and after hitting publish you notice typos or grammar mistakes? 

I personally hate it when that happens. I think that a grace period of about 3 hours would be enough to fix typos, missing links, YouTube embeds, etc. 

You can now edit bulletins, and you can also now preview bulletins like in blogs! (:
