Sorry folks, but I went down a wrong track with the `delay` node and how to tell it to _flush_ (dump?) all queued messages.

`return {flush: 1}` only sends the next message.

Is there a way to get it to dump all messages?

Thanks.

Ah!

Bit more reading.

`return {flush: true}` does what I want.

Sorry.

Didn't you check the node help in the sidebar before posting this Andrew?

Yeah, well I read it but it _didn't compute_ and I missed the latter part.

Brain is not as good as I would like.  
(Though it may be the language parser more than the bigger brain.)

I left the post only in case anyone else was too scared to ask.
