Last time I participated in one of these threads, someone who replied frequently to MY threads claimed to have never heard of me. Just like High School. 
Roland Orzabal is a B for me. I’ve seen you around frequently, but I can’t remember much about you. But, I’m sure you’re very nice.
hillbilly queen, you’re an A for me. Sorry.
:: hopes the next poster knows me, hopes the next poster knows me… ::
I’m actually… pleased!
Could it be? There is someone out there who… who doesn’t know? Who doesn’t know what ensues?
I think… I think I love you.
Sorry to disappoint, Ana. I remember all too well what ensues. You’re a solid p - er, C for me;)
Hey, you guys skipped right over me
Strinka, yer a B. I recognize the name, vague warm fuzzie feeling, in that you’ve never specifically pissed me off (I think)
You are a B for me. I recognize your user name but I can’t think of one detail about you.
cripes, this moves fast. Answered the phone to tell American Express to piss right off, and I miss three posts. Ana, and iampunha. You both get a C-.
maybe we should do the last three posters?
MrFantsyPants, you’re a B too. I’ve smiled at your user name, but beyond that, I’ve got nothing.
Hope I haven’t specifically pissed you off or anything. 
I rate koeeoaddi a B, but I bet in real life, he or she is a 10.
Casey1505, you’ve got over three thousand posts. I read the SDMB all the time. I feel like I should recognize your name, but I don’t. Crap, now I gotta go do some research… A
Hey, MrFantsyPants, don’t feel too bad, I’ve been ignored since the first page. I guess some of us just don’t matter. 
Both Casey and Lightnin’ qualify as solid B’s for me. I know I’ve seen the name around, but not much else is coming to mind.
I know JimSox5, but not too well. I guess that makes you a B.
Since I am new, I fully expect to be “A’d”.
Please! How can anyone forget a name like yours, Rancid? B.
AwSnappity would be an A, except that I THINK she used to be FireUnderpantsBoobs, which would make her a B.
LifeOnWry I have always liked your name. 
Ah sorry LifeOnWry, I’m sure you are a very nice poster, but I can only give you an ‘A’ rating. Mine’s probably on the way, so Karma will come back to me.
FlippyFly - B. Kinda. I considered a C, since I’ve seen you around a pretty decent amount, but I can’t really remember much in the way of context. Ah well – cheers anyway.
Oh, in in my last post to this thread, I mixed up A and C (because I’m just that good). I meant for iampunha’s rating to be a C…but I’m sure you all figured that out.
For me, Roland is a C. We’ve been in some of the same threads, and he’s an exceptionally gifted member of the world’s most awesome… message board.
Same here about you, LaughingLagomorph. I’ve seen you post often, but I can’t remember where or why.
I should really be paying more attention to Dopers’ names…
DarkSideoftheFloyd, you’re a B for me. I know I’ve seen your name on the boards quite a few times, but I can’t remember exactly where.
I need to pay more attention around here.
