Hi Haitem There are many good reasons for the site's rules and restrictions, one of them is the possibility that one colleague may suggest the best translation for one part of your phrase, while another may suggest the best translation for the other part, which creates confusion in points-awarding and in the glossary entry.
Moreover, it leaves the door wide open to all sorts of abuse.
Finally, the translation of slogans is often considered to be a separate job as this can be particularly challenging, so while you're not breaking any site rules, it's a great bonus that you're still able to draw on colleagues suggestions here.
Regards :-)
