What I would like to do is help to promote some of the smaller distributions, especially if you are yet to feature in the higher ranks of distrowatch and distrorank.
Getting people to use a distribution sometimes comes down to getting people to notice it.
If you admire a particular Linux distribution or you are a distro developer get in touch by emailing email@example.com. All I need is the name of the distribution and a download link and maybe a bit of background.
Getting a review is 100% free.
To write a review I install the Linux distribution to the hard drive of one of my computers and then use it over a period of at least 5 days. I then write my findings as I see them.
