If you didn't find more hoodies since the Gwynbleiid gig, you're out of XLs.
So far as Paypal goes, I haven't really used mine since last year and peeps can still send me funds if they know my username. Step 1 is to see if your account still exists. If it does, then make sure all account information is still valid. If it doesn't, register a new one. After that, it should really involve passing peeps the associated email address and filling their orders.
