Oh wow! :/
Well as you scroll thru the blog, when you see a picture etc. you want to reblog just click the bar under the picture that tells you the date the picture was posted & the number of notes the picture has. Then the page will come up where you can hit reblog or like in the top right hand side of the page.
(btw: the page is set to infinitely scroll so if u scroll down while on this page the reblog/like/etc. bar will move up. Just scroll back up to the top and the bar will re-appear) ☺
