Umm, editor Nyttend, you posted the following at my Talk page:

Stop introducing errors, as you did with this edit to the introduction of National Register of Historic Places listings in Allen County, Indiana.  Persistent addition of errors is vandalism and will result in blocking.    
This is your level 3 warning for introducing errors.

I take your threats seriously, as if you do mean to intimidate me from editing in wikipedia, particularly on Ohio and Indiana articles that you seem to take a lot of ownership over.  It happens that you have had disagreements about formatting and other matters in NRHP list-articles and individual articles.  I think you are wrong to imply that you will use administrative powers to get your way, and I do resent your several postings with "warnings" against me.  On the Allen County Indiana article, you have proceeded to make some edits removing material and making other changes, and I reverted you twice.  Where we are in a BRD process is that you removed stuff boldly, and I reverted you, and i think you should discuss the contenti.e. the MPS information, where the discussion is already going on and where I pointed to you.  You should not threaten to block me for disagreeing with you about the useful content.  I do think that cumulatively there are a number of disagreements adding up, where some bigger level review of your behavior is becoming needed. 

Anyhow I would like to clarify what you mean right now.  To be clear, could you please explain what you mean by a "level 3" warning, what do you intend to convey?  Honestly I don't know what you are intending to convey, what are you suggesting that I do.   I looked around a little searching on "level 3" and don't immediately come to any explanation.  Is the general gist of it that you wish to insult me, suggesting that i am a vandal?  You know that is not true. ncram
