How to change the login to register

Hi,

I've setup my homepage to login or register.
How can I change it to username when user has login?
So, I want it to be something like this.

From Welcome to XXXX. Please login or register to
Hello Andrew. Welcome to XXXX.

Hi,

My solution will be to do it with 2 custom HTML modules :
- 1 for non connected users
- 1 for connected users
You'll just have to use the "Access" option of your modules configuration page.

Do you know which custom html I should be looking at?

"You'll just have to use the "Access" option of your modules configuration page."
Where can I find this?

You'll find it through "Control Panel->Module Manager->'YOUR MODULE'".

Do you know which custom html I should be looking at?

I don't see what you mean. Just create two "custom HTML" modules as Mohamed said and type your text in.
If you need more information, please look into some Joomla's forum since it's not directly related to Hikashop.
