Please redesign to make sleeker and more modern looking

Two issues with posts in Groups:

1) The subject font is far too large and takes up too much space on the screen

2) On the Group profile section and the post itself you can't tell who made the post anymore. It does sup up as a separate section above the post. It needs to be in the post. On the Profile page you don't see the name of the poster at all. Posts in feed should look similar to this (attached from FB)

Group profile page needs redesign. For instance, if you go to the Testers group, and click on it it defaults to the Profile section (great!). But

1) It only shows two posts that take up far too much space on the screen (laptop) and

2) it is not clear how you load more posts
