Typoink and Typo Knig.
I still to this day sometimes do a double-take when I see Hajario :sciencefail:
Heart of Dorkness and Left Hand of Dorkness. I’ve been on this board 7 years, but it is only in the last two months that I’ve finally figured out what part of the username to pay attention to.
And that is …?
The non-Dorkness part.
Ignorance fought!
It’s taking longer than we thought…
Glad I don’t trip you up. BobT does all the time, and you do occasionally.
It doesn’t help that I often see posts that were actually written by me but feel like they were written by a different person…
Gosh, you are a real pal aren’t you? 
I always mix up Feather Lou and Cat Whisperer.
mhendo and the former MGibson (now Odesio). Years ago I used to have frequent conflicts with MGibson, so when mhendo very kindly showed me round the Mission District in 2010 I was initially somewhat confused…
Not to mention enola24607, EnolaGaia, and Enola7hmx
For those not in the know, Cat Whisperer is the former Feather Lou.
That’s silly. I’m pretty sure Lust4Life is British so the accent should give it away…
Well, that’s understandable - both are excellent, intelligent, articulate, wonderful posters who are a real asset to this site.
Oh, modest! I forgot modest!
Lobohan and myself. I scroll through a thread, think I see someone quoting me and bashing my behind thinking, “Who the bleep is this craphead and when did I write tha-- oh, that’s LOBOHAN!” 
But I like lobohan’s posts when he/she gets into it on a subject. Hats off! 
I always thought there was a relation, like Sam and Sam II.
Thanks Leaffan and Cat Whisperer. I thought my lame joke was going to be wasted
