A Queue?
ok so basically you just select "queue" instead of reblog and depending on what you set it to (how many queued posts post a day and in what time frame) it will post automatically at some point. all of this is easier with the add-on that i think most browsers have called "xkit"
for example when you mouse over the reblog button a little menu comes up that allows you to delete captions, replace captions, reblog posts, and save posts as drafts among many of the features.
