In my case, It is much the same as the rest that when I merit someone only the smerit is deducted and my merits is unaffected. I never know that someone is creating a thread complaining about their merit being deducted when they send a merit to someone else. Is there any complainant about it? I did not expect that there is someone who voted that his/her merit counter did decreased.
Maybe instead of +Merit button it could be +sMerit?
What I understand at first about the +Merit button is that senders will increase their merit and I don't know which one will be sent if it's your merit or smerits but now I understand it clearly.
