First of all, thank you for taking the time to propose edit suggestions to posts on Super User. [Your suggestion history](https://superuser.com/users/670755/timotree?tab=activity&sort=suggestions) shows that many have been accepted, which has been in line with the edits of yours I have reviewed. It's good that you want to learn more about why this one was rejected.

## The [proposed edit](https://superuser.com/review/suggested-edits/838327) was not substantial enough

Most of what you changed was reasonable. You left the title alone, moved around the intro sentence around, changed 'pluged' to 'plugged' and added a question mark. You also made a couple of minor phrasing changes which were reasonable as well, though it was not a huge difference. 

What *could* have made a huge difference?

## You could have inlined the image

The image which OP provided but could not inline in the post due to [insufficient reputation](https://meta.stackexchange.com/a/75498) should be present. If you could only make one change to a post, this is the one to make, as it makes the information immediately available in the post without having to open a link. I rejected the proposed edit on the basis that this should be done first and foremost - you have been with us on Super User for some time and as such [have the reputation](https://meta.stackexchange.com/a/75498) to do so.

This is one of the bullet points on the [editing help page](https://superuser.com/help/editing):

> Edits are expected to be substantial and to leave the post better than you found it. Common reasons for edits include:

> - To add related resources or hyperlinks

in addition to the other reasons, fixing spelling and grammar issues - as you did - included.

You could have made some other changes to the post, such as shortening the title or otherwise tidying it up. You might also have changed the tags, and a line break or two may aid readability.

I hope this doesn't put you off proposing edits! You have correctly asked a reasonable question about one of your proposed edits, and this should give you a way to make future edit suggestions even better.
