[ALUG] imap login slow

Hallo? Is this thing still on? Let's see. I use Betterbird and recently it's started to be slower at logging into my email accounts with imap. Not glacially slow, but not as nippy as it was. I have googled but I'd quite like some plain English advice about what I could try to speed it up a notch. Bev. P.S. And while I'm here, I have two Alug accounts. How do I ditch one of them?
