The only thing I might ask to be added is a list of appropriate greetings for certain officials. “Dear Mr. ” may not always be the only choice. You could add things like The Honorable, or Your Excellency… depending on what the official title of the person you are addressing. I had to look elsewhere for that. But everything else was covered here!! Thanks!

Should the block area be lg enough for two, or as the case may be, more hand signatures, OR should each signature be partnered w/ its typed name?

P.S. i came back !) to see what just happened & 2) to correct my spelling.
Thank you! Despite my apparent duplication, i have no
assurance that i will even see assistance, until next-never-day, as my Mother used to say the phrase.

Husband and i are trying to figure out the proper manner in which to sign our mutual banking letters, using both of our signatures and typed names.
Shall we block an area lg enough for the both of us to sign together, w/ our typed names below them, OR should we type our two names, leaving areas for each of us to sign, above our own respective names?

Regards is a one word sentance and is a shortned version of “Thanks for reading the above.” Putting a comma means that you are thanking (or giving regards) to yourself, as in “Thanks for reading the above, Mr Simmons.””

Actually, the comma IS correct. The single word ‘Regards’ is no more a sentence in and of itself than your name. As such, it does not need to follow proper sentence structure. The period, or full stop, is no more necessary than ensuring that the (to use your term) ‘sentance’ [sic] has a proper subject and predicate, or that the verb, or lack thereof, matches the subject.

You are reading far too much into the ending of the letter. The signature block was never meant to be read as if it were yet another ‘shortned’ [sic] paragraph. Perhaps you should read up on the matter.
