Just a few ideas Ted....

[The DJ 27]

Don't know how easy it is to add forums or anything, so this could be a total waste of time. But how about putting a "general" forum in the technical section along with engines? Just gives more scope for people wanting advice and stuff on non-engine things to post.

Also, (could be a bit controversial this one)

How about a Tuning forum? There are plenty of PH'ers with tuned cars, and I would imagine plenty of people who are planning too. Just a few ideas you understand. Keep up the good work

General technical is probably worth experimenting with.
