How do I post WTB in the thread?

I apologize profusely, I am a complete noob to this forum, and I wasn't sure where else to post this, or even how to DM someone to ask. Mods please delete if I'm breaking any rules. 

I am wanting to find an item to buy, but can't figure out how to post in BST, any advice is appreciated, thanks so much and happy to be here
