Thanks to you all. Looks OK to do it anywhere

My sincerest apologies Mr Vane. I was not intending to abuse in any way.
Rather than cause any further problems I will withdraw my question and seek advice elsewhere.

Thank you JAADAMS, most helpful. I tried to find the HMRC trust webinar site/notes without any luck. Maybe it will be recorded at some future date.
