Translations:Help:Growth/Tools/Enable the Homepage/5/en

Check on the $1 section for the $2. It will show another checkbox, called "$3". Checking this checkbox will make your username in top right go directly to Special:Homepage rather than to your user page. The target of your username will not change for anyone else than you, and it will not take effect anywhere else. Newcomers who have Homepage enabled have checked both checkboxes.
