A few ungrammatical (in English) error messages

[Boyd Johnson]

An example would be: Some usernames are unknown or no more active

Should I fix them by changing the msgstr in the en locale or changing the the msgid in all the files?

[Patrick Samson]

Could you provide a list of:

old message
new text
...

as an attachment of this issue (or in a direct message)

[Boyd Johnson]

Here are what I can find and how I would change them.

[Patrick Samson]

Changes are committed. Thanks Boyd.
