Have not had password/login issues but some of your other points have been "noticed" on our end as well. The very few sales overnight issue is there for us (sales return during the day) but sales overall (CCBill sales) are down for the past two weeks.
March IS a crazy month - St. Patrick's Day, Spring Break, March Madness (lots of gambling there), tax time right around the corner, on and on.
HOWEVER: It is upsetting when you notice 4 sales overnight, switch to another processer and WHAM! tons of sales immediately. Switch it back to CCBill and WHAM! sales drop. Could be a combination of things but......
Maybe everyone is focusing on the Phoenix Forum and that's why sales are down, or what I wrote above, or karma, or the Moon, or......fuck I hate March.
