Where to put an "Ask the [expert]" thread?

I have been urged to post an “Ask the high-peformance driving instructor” thread, and can’t figure if it should go in IMHO or MPSIMS.

There aren’t any “Ask the xxx” on either forum right now, and I can’t recall any others on which to search at the moment.

Is there a strong preference? Does it make a difference?

Thanks.

Here’s a compilation with links to the ‘Ask the …’ threads. From this outsider’s perspecive - it looks like the 4 work related threads were MPSIMS.

Thanks, John. Looks like there’s no hard and fast rule. I think I’ll go to IMHO.
