You'll find the English text in the db, cms_config_custom, in a record with cfg_name = member and cfg_fld = registermsg. Open with phpMyAdmin, and step through the file to find it - it should be within the first few pages.
You could either just replace the English text with French text, or if you wanted to display either, create a new record with, say, cfg_field = registermsg_f, and then modify /modules/Your_Account/register.php to display either English or French, by using the correct version of registermsg or registermsg_f depending on the current value of $currentlang.
Note that you will need to add $currentlang as a global in register.php first before you can test it. Also the contents of cms_config_custom are cached, so after you have updated cms_config_custom, you will need to delete the file /cache/config_MAIN_CFG.php in order to force Dragonfly to re-read the changed version.
OK, I'm pushed for time right now - but here's a different suggestion (this is for DF 9.2, if you are really on 8.2 you'll have to guess at the equivalent line numbers, exact line entries, etc):
Add a new line in /language/english/your_account.php at around line 61, or at the end, makes no difference, like so:define('_REGISTRATIONTEXT','. . . put copied text in here . . . ');
Then in module /modules/Your_Account/register.php on line 45: <td><span class="genmed"><br />'.$user_cfg['registermsg'].'<br /><br />'._BOUNDREGISTRATION.'<br /><br /></span><div align="center">
change $user_cfg['registermsg'] to _REGISTRATIONTEXT (ie switch it to read from the language file, like the rest of the page, rather than from the db), e.g: <td><span class="genmed"><br />'._REGISTRATIONTEXT.'<br /><br />'._BOUNDREGISTRATION.'<br /><br /></span><div align="center">
If that works in English, then you should just have to add the same new text line to /language/french/your_account.php, and to every other language translation that you want to support, and it should work.
Sorry I have no time to test this. Please report back if this works for you, as I'm sure others will need it - including me quite possibly in a future project. And post the translations that you have come up with for the benefit of us mono-linguists ?
Ok - I've found a variable that's named 'boundregistration'. I don't need two texts in registration so I decide to take this I don't know the differences but it works good for me. Thank you all.
I'll remove special corp. text and than post it here.
