1.  I did an upgrade from DNN 5.6.3 with Minimal extropy and all went well.  There were some funky things with the admin and host menus being just outline boxes with no content so I just clicked on the admin link, went to skins, and changed the skin to Dark Knight.  After applying that skin the admin and host menus rendered correctly.

2. I installed the forum module 5.0.3 included with the package. The install went well.  There are some rendering issues in the forum layout primarily in the settings menus within the forums. The little help buttons don’t really align with the the text properly. This is happening on Chrome and IE9 in both standards and compat mode.

 3. Superuser photo doesn’t show up in the posts even though they are “Public” in the profile.

4.  The DNN Favicon doesn’t really look good against the dark background of the search box. I suggest lightening the default color of the search box or revise the favicon to look good on both the dark background of the search menu and the white background of the browser url entry bars

5. Filemanager still doesnt work properly with Gzip compression enabled.

 There you go.  DNN 6 Beta 2 wasnt in the dropdowns, but someone can add that and update these items I suppose.
