There is no "Welcome....." "You last visited" and all that.. within the arcade, that is the
navbar that is displayed on every page.

You should really go to the thread for this mod to discuss your question.
Some members don't search the forum to find post about the arcade, they will go
to that thread. So, your question may sit dormant forever.

To add or remove info from the area within the "navbar", log into your
Admincp/Styles & Templates/Search in Templates, type in navbar,
select the style you wish this edit to be done to, click search.

Find:
welcome_x_link_y

That is the beginning of that area.

Remember, back up your template before you edit it.
