Creating a spiral tube

I have just received an email from the Sketchup Forum that reads as follows:

"We’re sorry, but your email message to [“sketchup+497ba4afae3baf81e2ea058706e3e014@discoursemail.com”] (titled Re: [SketchUp Forum] [PM] RE: Creating a spiral tube) didn’t work.

The topic you are replying to is currently closed and no longer accepting replies. If you believe this is an error, contact a staff member."

Anyone know what’s going on? @jody

I was trying to respond to a PM from @DaveR but it’s almost like he has been “cancelled”.
