Thread:Support/keeping a list of messages with some problems

What would you do, if you find a translation error accross a number of messages and you want share a list of them with other people, in order to improve them together? I could think of several ways to do it. However, none of the three is satisfiable to me.
 * 1) Make a index page and write links to those problematic messages.
 * 2) * It would be difficult to keep it update.
 * 3) Assign a category like Category:Ja_questionable_messages_regarding_FooBar to each message.
 * 4) * It might destroy the interface if such categories aren't ignored when included into MediaWiki.
 * 5) Add some mnemonic comment like  into each message, making it easy to find with Special:Search.
 * 6) * I don't know if the search works in that way.

Is there any other cleverer way?
