Ultra Axiomatics:

• There is a new useful feature for reading the Usenet posts in Google Groups. The vast majority of newsgroup members use GROUPS.GOOGLE.COM to post and read on the Internet pioneering service, Usenet.

One drawback of the Google service, very useful otherwise, is the default font. It is a proportional font (of variable-width, that is). However, initially Usenet was written and shown in a monospace font.

Many of the statistical reports I posted over the years did not show up in an acceptable format. The original format was in the typewriter format (the Courier font). I shall inventory the most important posts in this newsgroup and refer the readers to this important thread. Viewing will be better off overall.

It is quite easy and simple to add this useful feature to two of your browsers: Chrome and Firefox. Just read this axiomatic thread:
