Sorry, yes i would like to change the actual reputation of the user in a mongodb database.

Hello,
How can I change the reputation of a user inside a widget ?
For example increment by 1, reset to 0, etc...
Thank you.

How can I show something like : "Hello xxxxx, you have xxxx reputation" on a welcoming html widget.

Is it possible to use these variables to do something else ?

For example :
if(reputation>50){
//SHOW SOMETHING
}
else{
//SHOW SOMETHING ELSE
}
