Hello/Hola
 

Hello everyone, Hola a todos!

My name is Joy, I am from the West Indies and want to practice my Spanish with you.

Hola a todos! Mi nombre es Joy, yo soy de las West Indies y desea practicar mi español.

Gracias mis amigos
Thank you my friends.

[i am not certain about my Spanish, kindly correct if I am wrong]

Hola. Welcome to the forums. :)

¡Hola a todos! Mi nombre es Joy.

If you use an exclamation mark, you need it at the beginning and at the end of the sentence.

Also, the 'yo' isn't needed because the present conjugation of the verb 'ser' determines the person.

However, it can be sometimes added for emphasis because generally they're not used unless you want to emphasise the person.

Welcome to the forums, Joy.

In addition to the corrections already given, El Caribe is where you live and you need to correct the person used for 'desear'. You didn't translate 'with you' into Spanish. Any reason why?

Hello Joy I'm George from Mexico if you need to help with your learning please you don't hesitate to ask me anything you could need it:)
