Lou:
I can think of two ways: 1) modify your handle (or nickname) for the Forum,
or 2) add you affiliation to your signature when responding to a message
posting regarding your product or a competitor's product.
This purpose is simply to enable readers to know that your information –
when discussing your products or a competitor's – may have a certain bias.
There is absolutely nothing wrong with bias, if it is clearly identified so
that the reader has complete information about the source and his/her
orientation.
Hope this helps. — Rich Bowers
