I saw an interesting post sometime back but with no solution. Trying luck here:

There is a table which contain 10 names (U1, U2, U3..and so on). I have to choose 5 names everyday, and display one as the Editor and 4 as Contributors

While selecting the random names, I have to also consider that if one user is selected as Editor, he cannot become editor again till everyone got their chance.

The output should look similar to the following:

           Editor   Cont1   Cont2     Cont3    Cont4
20-Jun   U1      U8       U9         U3       U4
21-Jun    U7      U2       U5         U6       U10
22-Jun    U3      U4       U9         U2       U8
23-Jun      U4      U8       U3          U5      U2
and so on..
