The Moderation Log is for things like posts and topics getting deleted, topics getting moved or locked, and similar acts. It's got nothing to do with moderation of individual posts. I suppose one could add a message there if some post was not approved.

Many translations are missing localized texts for more recent features; we only rarely get people to help on that. If you can supply missing translations, we'd be happy to include them.

I looked at the translation files. The ru_RU.properties file contains keys that are not in en_US. properties. For Example, Config.Form.HotTopicStart . Which file is the root file? Please note that I do not know German.

The en_US and de_DE files are fully up to date. If something is not in them, it's safe to assume that it is no longer used, and can thus be ignored.

Hot Topics, for example, were changed in this release. COnsequently, Config.Form.HotTopicStart is no longer used, but there is now Config.Form.HotTopicPercentViews. Russian is also missing RSS.HottestTopics.description and RSS.HottestTopics.title (the latter being just about identical to ForumBase.hottestTopics, so don't bother with that one).

Deleted the unused keys you specified.
Translated the lines whose purpose I was sure of.
I hope everything will be right. I'll test it again tomorrow.

There are two messages left to translate. But I don't know how to translate them correctly yet.

That's terrific, thank you very much. It'll be in the next release of 2.7.0.

There are just a few more missing texts for the Russian translation (6, to be exact), if you're inclined to help out one more time. See https://jforum.andowson.com/posts/list/172.page for the details. There won't be more, as the release is otherwise feature complete.

I didn't quite understand this message
Config.Form.HotTopicPercentViews = Hot topics geared more towards views (100) or replies (0)

Everything else is translated

And more. I have Netbeans some files as erroneous
For example,
https://sourceforge.net/p/jforum2/code/HEAD/tree/trunk/src/main/resources/templates/default/js/moderation.js

One of the erroneous lines 17 (there are other similar ones)
alert ("${I18n.getMessage("Moderation.Select Topics")}");

Thansk again.

I didn't quite understand this message

That's understandable, and we just changed that feature to be simpler. So the property is now

Config.Form.HottestTopicsSort = Sort Hottest Topics by views (true) or replies (false)

It means whether the list of Hottest Topics contains the topics with the most views (as it is now), or with the most replies.

alert ("${I18n.getMessage("Moderation.Select Topics")}");

That's OK. NB thinks those are pure Javascript files because of the ".js" file extension, and flags invalid syntax in them. But what's happening is that the template engine (FreeMarker) replaces the "${I18n.getMessage("Moderation.Select Topics")}" part before it sends it to the browser - so that they become valid Javascript.

I suspected as much about js
Added translation of the last message

No, sorry, the missing property is now this one:

Config.Form.HottestTopicsSort = Sort Hottest Topics by views (true) or replies (false)

Config.Form.HotTopicPercentViews is no longer used

IN

Sort Hottest Topics by views (true) or replies (false)

Do I need to translate the words TRUE and FALSE?

Yes, and they should be the same words as the entries for "True" and "False" that already exist in the file.

Fixed the translation, deleted the extra key and added a new one

Again, thank you! This makes Russian one of the "complete" languages (less than half of all supported languages have completely up-to-date translations).
