That's understandable, not everyone wants the attention.
I know a few heavy collectors that never advertise what they have or any details that would help find who they are...
Yeah, I get wanting to remain unknown, if only to keep people from showing up on your doorstep (I don't want visitors, really,) especially as someone who is not involved in social media, you won't find me on any of the locator lists, etc. Though, I'm sure I have spilled enough info here on AO for someone to put together a fairly good guess

I find the big shame to be not so much the equipment but the knowledge which is held separate. Honestly, while none of us have a requirement or responsibility to share knowledge with each other, I bet there is a lot of untapped knowledge and experience out there.
