Hi Team,

Two issues i need your help with:

1. I’d like to organise posts by a user, using the blog masonary style, embedded in the Tab accordion..

I.e. Can you reflect: http://hb-themes.com/themes/highend_wp/blog-masonry/ but just 2 columns?

I have attached a screen shot, and this is the link to my site. http://www.hellohaus.com/my-profile/

2. For blog posts, when you run your mouse over it, a greyish black cover runs over it with a + sign. Can i remove the greyish black cover, and just keep the + sign?

Thanks,
Wanling
