Based on this post, pepperlandgirl said that she’s growing tired of her username and would like another one. She’s a self-described Beatles fanatic, so I’m guessing she’d like to keep it Beatles-themed.
She herself has suggested Muzzle of Bees or PepperLG. I personally vote for the former, as I like the imagery it creates in my mind. 
Any new suggestions?
Harrumph. No way, she’s one of us (we?) Buffy fans! Must be Buffy themed. I nominate Miss Kitty Fantastico.
Combining a Beatles song and a John song, how about Power to the Pepper?
paydepwahv (for pays de poivre, French for “pepper land.”)
How about Pepprita’?
Is Strawberry Fields too pedestrian? Rubber Soul?
How about something like My Bird Can Sing?
(Her location field, of course, would say “Here, There and Everywhere”)
Let’s see… what rhymes with Utah?
Okay, all I get is Puta and I ain’t even goin’ there.
(Heh, pepperland’s a pm bud, she knows I adore her.)
Prudence? A Beatles reference with old school charm.
ETA - I was named after a Beatles song in real life. So for some reason I always feel like a long lost sibling to someone when I see a Beatles name on the board.
“Polythene Pam”?
“Eleanor Rigby” is out of course.
pennylanegirl? 
Polythene Pepper?

Oh, I saw my name in a thread title and thought “Holy crap, am I being Pitted?”
Yeah, I’m that paranoid.
I really like some of the suggestions, including CremeTangerine, Polythene Pepper, and **paydepwahv **.
The reason I’m considering Muzzle of Bees is that it is my favorite Wilco song. I even, well…I have some of the lyrics from that song tattooed to my body (Half of it’s you/half is me). I also like the idea of something BtVS/AtS related.
But on the other hand, I’ve been pepperlandgirl for so long that everybody calls me pepper, even people I know IRL (Heck, it’s my professional name now). So the thought of changing it makes me hesitant.
Of course, you could combine the Beatles and Buffy things…
