I was presented to sendy by you. Thank so much. The product and the module are awesome. I need translate the messages of module to portuguese and I can´t find a sentence: "Already subscribed." I know that there's no override by ini files, like joomla default. I found the others sentences directly in *.php files. Could you help me to find this?
I'm happy to hear you like Sendy. We still use it and like it quite a lot. We never sent enough newsletters to make Mailchimp worth it, so the savings alone are great.. and Sendy keeps getting improved.
As for your question about translations, you're correct.. we don't use Joomla's language files for it. There's only a few strings, which isn't a good excuse, but it is what it is
For the specific strings you're looking for, though, they are actually responses from Sendy itself. You'll need to look in the subscribe.php file from the Sendy folder and search for the strings you want to edit. It's much uglier than what we provide.. so we look good there at least.
I hope that helps, but if you have any questions or issues, just let me know.
