Improve explanations of usernames

[kjetilk]

This should implement #823 and also address (at least partially) the bug in solid/solid#205 by downcasing usernames on submition.

[RubenVerborgh]

The explanation is clear.
There's just something wrong with the commit sequence; needs rebase.

[kjetilk]

Right. It is just that stuff seems to happen every time I rebase, and I end up having to do a merge anyway...

[RubenVerborgh]

@kjetilk Ping me if I can help.

[kjetilk]

Yup, I will @RubenVerborgh , just need to investigate a bit more myself, to see if I understand the pain point.

BTW, the Snyk failure, is there something we could cherry-pick for that?

[RubenVerborgh]

@kjetilk Just a rebase on develop will do. The following should work:

git fetch
git checkout fix-username-docs
git rebase -i origin/develop

Then pick only the commits you need.

[kjetilk]

OK, so perhaps this is what happened: I merged the 5.0.0 branch into it...? If so, that was certainly an accident. I probably meant to merge develop into the 5.0.0 at that point.

Anyway, let me see if I can rebase it successfully with that understanding.

[kjetilk]

OK, so how about now?

[RubenVerborgh]

LGTM. Maybe squash merge?

[kjetilk]

OK, I usually look at commits as the gory details, but let me do that to experience the difference :-)
