I sent off a whole bunch of spam to the translation teams, Last-Translators, and gnome-i18n to get the .po files up-to-date for Pan 0.13.0. Typically string freezes and calls for translations don't do any good, so with 0.12.0 and 0.13.0 I'm trying bribery -- one of the people committing a complete translation will get $25.
I talked to a couple of the regulars on #i18n at irc.gimp.org to get ideas on what, if anything, I could do to get more translations up-to-date, and have cleared out a lot of duplicate/redundant strings.
The real issue is probably that Pan is a niche project, so I'll probably have to keep banging the drum to get attention if I want translations.
Maybe there are other motivators. Recognition is important -- I should make sure translators know their names show up in Pan's Help|About|Translations list?
Or maybe another contest could have the winner name the release (the release name shows up in the User-Agent header of Posts written with Pan)?
