I was about to donate just now but the site started asking for my name, address and other personal information in order to allow me to pay. I don't mind donating to Nexus, even if it's $5 or $10 I'd still do it. But I don't want to register my personal information on a site unless I really have to,
I would suggest making the "Ad Free For Life" option an $2-5-10-25-50 choice instead of the current $1.29, and then adding PayPal as a payment option. I'm certain you would get more donations that way than what you get today.
