to be fluent not fluently..

Also, the last phrase: Just text me, or message me, I don't think "text a message" is good phrase. 

Thank you Sarah👍😊

If anyone wants to learn or practice Arabic, I will teach you to be fluently.

I think it's better.

Sorry, fluent not fluently!
Fluent is adjective. 
Fluently is adverb. 

Thanks👍😊
