Develop blog functionality

I'm looking to have some existing blog functionality improved. Currently, when clicking a post on the archive page, the post loads in a modal. The two below points need completing. - URL needs to be updated to current post when firing modal. - Single post template needs to become a modal, so when a user comes on from a post URL, they are directed to the post archives - then the pop up appears. Functionality the same as - [login to view URL] You'll see what's been completed so far - [login to view URL] Automated bids will be ignored, so please have a look before.
