Merci pourde lire ma premieère reédaction dans cette forumsur ce site.

LG has a forum but this part is just the main site, technically
"merci de" means "thanks for doing smthg", it can express gratitude but also a request. If you want to disambiguate and make it clear it's gratitude, you may say "je vous remercie beaucoup de lire [...]"

Je vous remercie pour ta corrections. C'est tres tres utile!

You're welcome! Yes, "nerveuse" is the feminine form. "Dans vs sur" in French very often matches "in vs on". All apps, softwares etc require "sur", for instance Adjective position is trickier, though. Some adjectives even mean different things according to their position! Un musée ancien = an old museum Un ancien musée= a former museum But the more French you'll be exposed to, the more natural it will seem!
