Birthdays & PMs

I have two questions about my forum:

My first question is, how do you change the amount of days it builds up for the birthday? Like at the bottom, when it says "Users with a birthday within the next x days". How do you change that?

Finally, recently I received a spam private message from a guest on my forum. How do I make it so guests are not able to send PMs?

1. Administration Panel > Users & Groups > Users > Users Options
Birthdays Section
Birthday look forward:

2. Guests can not use the private message system. Did the pm you got have this in the title [Contact]?

Yes. It was asking for a business partnership or something, I believe and included an email address.

That means that the guest used the contact link at the bottom of the page. These private messages should only go to the administrators.

You can turn it off here:
Administration Panel > General > Messages & Emails > Emails & Contact Form
Contact Form Section
Activate: No
