Hello EverlastingPrinter,
I believe this would be more based on your account level which is increased by completing achievements.   I will verify with the team and have a more definitive answer after the labor day holiday.

Have a good weekend!
Regards

Thanks for your patience.

You must be a member for at least 30 days before you can send private messages.  We will add a notice in the messages section shortly so new members are aware of this rule. 👍

Hello EverlastingPrinter,
VIP members will be able to send private messages without restrictions. You can get VIP for free by clicking 'Upgrade to VIP' in the left menu bar.  

You should have access to the private messages on Monday once this VIP feature has been implemented.

Regards
