hello,
-what is difference between module / component versions? Are there different versions for PRO also?
SefTranslate features you may see:
www.ordasoft.com/SEF-Translate/seftransl...ture-comparison.html
-Is it required to have joomla search-engine-friendly urls or are default urls ok?
For SefTranslate Pro and Commercial version, for redirect mode - that require. True say that not require, but as SefTranslate Pro redirect and "joomla search-engine-friendly urls" require turn on HTTPD server "Rewrite mode", so when you will use SefTranslate REDIRECT mode - you will take and SEF URLs
Thanks,
OrdaSoft team
