In reply to Piet.

See, there is a big difference between a user of a free plugin and a paid client. If a client is paying you, the trust factor is probably already there. A developer of a free plugin I'm using doesn't not get my trust automatically. I do background checks etc but it's been a long time since I've had to give a dev Admin access to the site to see the problem for themselves. That's what the screen sharing is for.

If I give you money, you sure as heck better fix things and do so without losing my data :)
