How do you link to a room on your habbo home?

Widgets in webstore :)

or find out the url that goes to your home from the widget

and make a normal link

[Shawnstra]

On your homepage, or in other people's homepage (guestbook), wherever you can enter BBcode, just type in the room name in the search box (check on room first), and click the correct link.
