Dan O'Neill Hi Dan, sure thing. Just sent an e-mail to support@brickstuff.com with more details of what you're trying to achieve, and include any photos if you have them. I'll pick up the ticket there and we can continue the conversation. If you'd prefer to talk via phone, we can do set up a call as well.
