Sounds like you're trying to reply to a message in Cannabis Connection board - you may only reply to your own messages there; post a new thread. That restriction there (the Cannabis Connections board) encourages folks to reply to folks about connections, etc privately via PM, IM, email, etc instead of publically.

In regards to posting history ... these cann.com boards have only been up about a year and half - try http://boards.marihemp.com/ - perhaps you're registered there too.
