(Small update) Billing model switch

Switching, at last, to the "pay the day you joined each month" instead of the "on first of each month" i had all this time.

It should be better for most people now, i can imagine.
Why did this took me so long to do? It was more convenient for me personally due to how businesses work here, which was inconsiderable. And i never given it enough thought before, I'm sorry.

Those who are subscribed currently / joined prior to today are not changed, still on the "first of the month" format, sorry if this is an issue.
