Based on this thread I first figured out how to go from the old Paypal website to the new Paypal Credit website.
Once there, the first thing asked was to update income. I then decided to request a CLI to $10,000 just for grins and suprisingly it was approved. (My limit had been $2,100 since I opened the account in 2005, then last year it was auto-increased to $3,100)
BIG CONGRATS @MaizeandBlue on your 3X PLUS PayPal Credit CLI - That's how it's DONE!!!
