I tried addressing a PM to two names separated by a comma but that didn't work.  "No such user as name1, name2"  At that point, I didn't want to take a chance on addressing it to "name1 name2" (no comma) and not know if it got sent to both or only one.  I tried addressing To: name1 and Cc: name2;  name1 replied but I don't think the PM got to name2.

....you have to pm each individually, there is no group pm. But I have been wrong before.

if you don't have the right name there, obviously it will not deliver.  Other than that, I don't know what to tell you.

As usual PS has it right, simply use the CC function, just like you would do with an email.

One thing to remember however is that TER has strict rules about sending spam, using the CC function to send out ads to multiple members for example is a good way to get kicked off the boards.

I will never claim to be the perfect storm, I am a mere mortal prone to fallibility.
