Extension that allows user to submit lists w common queries? - Joomla! Forum - community, help and support

i looking extension can allow users submit list , assign matching field entries. intention use site grade baseball prospects (users submit top 10 lists , assign grade each prospect).

i think example easier understand applied function allows users submit top 5 list of hot babes , assign grade them.

for example user submits
1. megan fox 98
2. halle berry 96
3. jessica alba 95
4. olivia wilde 93
5. kristen stewart 92

user b submits
1. adriana lima 99
2. jessica alba 97
3. olivia wilde 92
4. kristen stewart 90
5. megan fox 90

if these 2 entries, community list take mean of responses per entry , result in following
1. adriana lima 99
2. jessica alba 96
3. halle berry 96
4. megan fox 94
5. olivia wilde 92.5
6. kristen stewart 90
