OK, finished sooner..... :)
Unfortunately I cannot give you any URL, since this is the project of someone big in Greece...
I'll probably make a test-site and let you know.
Now, here is the translation of the Greek Translation Team's manual:
Step 0 (necessary for every committed change): create backups of your content files.
Step 1 – Files
and download the necessary files. These consist of a component (Mambelfish_1.5.zip), a module (mbf_module.zip) and a mambot (mbf_searchbot.zip).
Step 2 - Installation
Install the downloaded files in the following order:
a. module (customize and publish it)
b. component (commit the necessary customization). We have tried this installation with 2 languages, not more [my note: I communicated to the Greek Forum my experience with a third language]
c. mambot (publish it). This one is useful for the multilingual search capability.
Step 3 – Patch files
Following the component installation, please locate the directory components / com_mambelfish / patch; choose your version of mambo and copy these files to the appropriate location on your server, overwriting the ones already existing.
Step 4 – Setting parameters
a. Through the module, you define the appearance order of every language, as well as some more features about the language appearance.
b. Through the component you define the languages for your site, the text which should appear when there is no translation for this language, as well as features about the language appearance.
Step 5 - Translation
In 2 words, the pain’s taking job: Through the menu components > mambelfish > translation, plase select the items you wish to translate and publish the new texts.
In our trials we were not able to use TMEdit, and used MosCE instead, which was a success.
