Welcome Kermit80. I lurked a bit too before taking this step to join in. I then combined lurking and participating, then life got in the way of the participating very often, with a few intermittent bouts of increased activity on here. Recently I've tried to be here as much as I can, not just because we're under house arrest in the UK, the longer I lurked and participated the more I realised that MT is a very worthy forum, some really good people and loads of informative posts. It sounds like your background will mean you fit right in here. Enjoy.
