@All
Coward
Look, I realise this is jut a bit of harmless goading, but in a rare moment of seriousness, I'll explain why:
Cowardice is not the issue, respect for the owners is. When real problems have arisen, I've waded straight in to fix them without asking and waiting for permission since it's understood by all that the sooner they are fixed, the better. I don't own the site; the past and present owners have placed a significant amount of trust in the fact that I only access the server when something really is wrong and needs fixing and not to make arbitrary changes (no matter how harmless) for fun.
If you paid 10K for a site, would you be happy with unauthorised changes to it's branding by one of the site members?
