If it's not really about tuning or wiring. Then it belongs in here.
It would be nice to have access to speaking to other members by having their emails. This can be one very easily upon registration whereas the member has the option to publish his email so it is made public to others. Sometimes trying to reach a member via the forum does not work that well.
I like this idea, but I think private messaging within the forums between members would be a little bit better.
