[Lugstuff] new stuff learned rebuilding Annapolislinux

Wed Jan 20 10:26:08 EST 2021

 Clarification:  I am referring to the textual component of the logo, not the text in the content of the Web site - i.e., "Annapolis Linux Users Group" in the banner at the top of the site's home page.

  Ted,
The logo is better than excellent, but part of the text is lost when window is resized upward.  I tested this on two computers using both Linux and Windows.  What about changing the format of the textual component of the logo from its current format, whatever that may be, to .png - a scalable format, or integrate it into the graphic since the graphical element maintains its integrity during resizing of the window.
I don't want to beat this to death, but I know you have put a lot of work into this and you want it to look good.

 Hey Bob,

Mailman rejected it saying the message body was too big.

You should be able to send large messages now.

I removed the header size limitation in mailman.
