Quick Question: Is there a way to limit/prohibit new members from sending PMs to people without first posting themselves. I received an PM from Summertree Hi Cos, Sorry to bother. We see you are veteran in this forum and very professional on audio gear. Just wondering do you happen to accept sample from manufacturer and help to post product review? We have an Infrared (IR) Remote Control Repeater with high quality, it’s easy to install and with great signal to control A/V equipment for amplifier, cable box, stereo receiver, Satellite TV receiver, CD player, DVD player, Blu-ray player and much more electronics appliances. Please see link on Amazon for more details: http://amzn.to/2tAY8Vl By the way, we also have a perfect Microphone Stand if you might think about a broadcast or other use http://amzn.to/2t8btmN Would you please kindly let us know your US address if you are interested in? we will send the product out. We invite you for this review with best and deepest sincerity, really hope we could have the opportunity to cooperate with you, we would be highly appreciated for your kind reply. Not a big deal, but this is obviously spam, I am not sure if it's possible and by no means a big deal, but just a suggestion.
