From the home page (https://www.painttalk.com/) just look for the forum that seems most appropriate for what you want to ask. "General Painting Discussion" would be fine if in doubt (https://www.painttalk.com/f2/). But - just for example - if it's specifically about "Green Painting Practices" or something, then there's a forum for that. So from the home page click on that one.
Then - for whichever forum you click into scan your eyes down from the top left past the blue bar and past the annoying ad that has the sh** on the page jumping up and down and find the blue button that says "New Thread" - it's right above where a lighter blue bar starts with "Threads in Forum:..."
