At first we would like to thanks for your ever-support for Sothink products!
Recently we notice that a small fraction of users use the forum PM for advertising purpose, which cause inconvenience and even unpleasure to others.
To have the above-mentioned situation under control, we decide to grant limited privilege for registered users regarding PM usage --- users could read (PMs from support members) but could not write a PM; to be clear, PMs are Read-Only for registered users.
We feel sorry for all the inconvenience & thanks for your understanding!

If you need any assistance, feel free to let us know.
Have a great day!
