I always do, even if it's red rep. Well I always put "- TS" at the end, people work out easily enough who it was
I always add my username, whether it be +/- rep. If its a +rep i'll just put my username and a smiley, whereas a -rep will be a comment with my username and a smiley
leaving it with red rep makes for some interesting PMs sometimes...that's my favorite part...lol... i think all rep should just have the username who left it included...if you don't want the person to know who left it...what's the point in leaving rep at all? jmho
I sign it. red too. what do I care if they try and get me back? I make quality posts and get greens daily, that more than makes up for anyone retaliation.
I almost never give red rep, so that's a moot point. I give green rep often when a post is helpful or informative. I always sign that rep with a comment and my user name.
Now I am going to start putting -Stax at the end of all my red reps... I always sign the greens. Not so that they will rep me in return, just so they will know it was from me. Sometimes I will sign the reds, but not always. It depends on why I am giving the red and how mad I am about it... I don't give very much red anyway...
I like to add someone else's username when I give reps. It's pretty cool, you should try For example: "I hate you ~buffalo", "kisses ~Denise", "Have another infraction, Crazy_Rob"
