I can understand what you wrote here, although I won't venture to try correcting you (if ever it's needed) since I'm a beginner myself! It's awesome that you're already making attempts and immersing yourself in Na'vi: it's really the best way to learn!

Hope you'll have lots of fun learning this wonderful language in this wonderful community. Never hesitate to ask for help when needed and don't be afraid to make mistakes!

Kaltxì ma tsmuk!  I know you will find a very warm welcome here!

This is a wonderful community where people are always happy to help you.  I know, because I'm just a beginner myself, and everyone has been very kind and patient.  Good for you, jumping right into writing niNa'vi! I hope you'll have a great time learning this fun language.

btw - I'm pretty sure that you must use tsnì with sìlpey but I don't feel competent to correct the sentence for you.  I still have a lot of learning to do.

Kaltxì ma tsmuktu, ulte zola'u nìprrte'!

It's always a pleasure to have new learners join us here, and you're certainly off to a very good start.  One very small correction:

Sìlpey oe futa piyevlltxe oe nìNa'vi nìltsan

As others have mentioned, an oddity of the verb sìlpey is that it uses the conjunction tsnì, and then what follows uses the subjunctive.  So, just swap futa with tsnì, and you're good to go =)
