That's strange but some time before it worked correctly. Then I had found that some symbols get lost when sending bb-mail(I'd been non-supporter). So I couldn't make some links including symbols /, = and some others. It made me annoyed, as no link could be sent..
But then I became a GM and received free-supporter and the problem disappeared. But sometimes I send the bb-mail to non-supporter with [player=xxx] and receive the reply with [player xxx].
It's very annoying
