Hi,
1) On Ja Social II and JomSocial the top menu and sidebar (the black one) when I use mobile phone have this layout:

Do I need already the sidebar? why the mail goes under the black menu (sidebar)?
How to make it seem your demo site?
2) How to have "Hi Jessica Davis" like in your demo?
3) The left and right module positions that I use for AdsAgency zones hide in mobile so how can I do to have this advertisment also on mobile without making an unusable site?
Thanks!
