Could somebody explain what "Marked" means in e.g.: "Marked game versions in which this add-on is included.". Is "marked" used as:
- The versions that are marked (with a tick)...
- The versions that look different...
- The version that are special... (the first ones of a new series?)
Also: "Apache Rewrites"
Is Apache being rewritten or is something written to Apache again? Or the number of retries Apache has done in order to write something?
I agree that the first string, "marked game versions..." is somewhat vague. The intent is to display a status message that the information about whether or not this addon is included in any versions of the game has been saved. (Example, Minigolf has been included from version x until latest svn)
As for Apache rewrite, yes, this is a technical term relating to Apache httpd (web server). This string also only appears in the administrative backend, so I think even if it was to be translated, it's not too important to do so.
For error messages, many projects don't even make those translatable, so I don't really see these as important to translate either. It doesn't really add to the user experience to do so, but for the sake of completeness, I try to at least include them in the list of strings.
If you have any suggestions for improved English strings, let me know. I'll update what is obviously bad and try not to break existing translations where possible.
