What does it matter whether Protool can answer those questions or not? As an AV pro myself, I can tell you that they are the kind of questions people who read camcorder magazines too much would ask. You could get by doing very good wedding videos without knowing the answer to most of them.
If someone has put out an ad suggesting a scenario, in this case videoing, why not leave it and see if people are interested, rather than attacking the guy on the assumption that he is a 'perv'. The response of the community will guide him in how to phrase his approaches if they don't work.
We're all here looking for a way to enrich our sex lives. It's way too easy to attack single men in this way. Most of us are as nervous, vulnerable, curious and in need of help when we start out as everybody else on this site. I would have hoped that a site like this would be one of the places where you don't feel judged for being honest about what your sexual wishes are, as long as they aren't illegal.
I'm glad that protool has reacted in a measured and open way, but I get angry when people treat single guys trying to make a connection as somehow dirty, dishonest or perverts.
