Unable to send out mail today. Can't even contact SB. 
It keeps asking me to input valid recipient username for some reason.
I contacted sb for you. 
Thanks pal!
Are you even a member 
Just kidding.
But in real life, I was unable to send you a (test)PM.
Hi freeme and everyone else, sorry for the hassle. I just increased the PM limits on freeme’s account.

Happened 2-27-21 It started working on its own. PM limit?
Awesome! It seems to be working now. Thanks for taking out your valuable time for me. 
Yep, same thing. Let me know if this happens frequently to you and I can also raise your limit.
No worries. was selling a few lights and had sent several PM’s.
I am sure I will be fine.
Thank you SB for all that you do.
Sorry boss... I think i hit the limit again. Does clearing my mailbox helps? Or new rule limits the amount of mail sent per day? I used to send out a hundred without issues.
No need to clear your inbox. I adjusted the limits again. Sorry for the hassle.
Do you mind asking how many PMs are allowed to send per default? Just curious... ;-)
I’d prefer not to give details in public so that outsiders don’t try to game the system.
I have been experiencing this same exact issue with random people I have tried messaging over the last 3-4 weeks.
Edit: I just read the whole thread.
Sb- it had been happening as I have been selling light over the last 3 weeks and sending many more pm’s then normal. If I happens again should I just message you? Or can it be raised in my account? Either way. Thanks for the help!
Sure, just message me if it happens again.
That’s a valid argument, indeed. It’s a mad world out there and it takes more and more security precautions. :-(
