I see this in each poster's profile. What does it mean

NKT:
When you log on you will see "Applause this members' contribution" and "Warn others about this member" right below the Forum Citizenship. If you click "Applaud..", it adds a point for citizenship. Atleast that's what I found some time back. So that's the + . So I presume if you click on "Warn..", it might add to the - points.
It's probably to give recognition to members for their contribution.
That's correct, cognostechie. It's a forum karma thing - when someone helps solve a problem it's customary to acknowledge the contribution by clicking on 'Applaud'. This adds to the '+' for the contributing party. This way, other users can gauge how good/helpful/reliable another user has been.
I might, however, just re-format the numbering system from '+/-' to just a single number (eg. instead of +5/-1, just show '4')
