Find Marmotry's lonely, abandoned alter-ego at 43T

Marmot,

Think hard. What can you remember about your alter-ego that may help us in this mission?

But I have some guesses on who Marmot3 (In the style of Marmot) and Marmotslave (The ACME Handwriting Analysis bear) could be.

I pick:
Marmot3 is Rouenpucelle.
Marmotslave is Captain Spiffydoodle.

What do you think?

But I have a question for GrammaG (or anyone else who knows)

The Search feature in 43Things is very, very specific when it comes to finding people.
When I type “Marmot” in the search field, it only yields me people who are exactly named Marmot. Like this guy.

Search does not yield “Marmotry” or “Marmot3”.

How did GrammaG find Marmotfan and Marmotfanfan?

here.

Somewhere at 43T lives a poor, sad alter ego.
