I'm new to ScubaBoard and would like to send a DM to the seller of a dive computer. When I tried to send a DM, I received a message that I need to post 5x before being allowed to to send a DM.
Post in the thread offering the computer requesting that the OP send a DM to you. You can answer DMs as a new member but you can't start them due to spammers who abused the feature.
