This is simply one suggestion about wpmu.org and i think is helpfull.
I like to read every night at bed the blog from you but i have a problem that for me is imposible to find the SEARCH BOX in order to find specigic stuff. And it makes very difficult navigation.
In desktop version it exists but in tablet version it disappears.
As a refernce my tablet is samsung galay2, 7".
I hope it helps.
