It's taken me a while to work out how to do some things on this site:
* At top right under your name is 'Settings'. If you go into the 'Email' section you can tick which activity you want to be emailed about. So then you'll get an email with a link when something happens - eg someone replies to your discussion post. Also on 'My Page' (one of the tabs in the red menu bar at the top) there is a link to all your discussions etc..
You might want to check the privacy settings in 'Settings' too - especially the last section which says who can see what you put up (eg entire web vs just your friends etc). It's not recommended to put email addresses or home phone numbers on your profile page (everyone on the internet is able to view your profile page).
* I've made a BLF folder in my email inbox, and a sorting rule. My email service (eg outlook express) finds everything with 'brisbanelocalfood' in the from field and files it in the BLF folder for me, so it's all in one spot and I get to it when I get a chance. Less annoying.
* At top right under your name is a heading called 'Inbox'. It's an onsite private email system. No one can see or read these emails except you and your correspondents. Use this system to post contact details etc. Add people to your friends list so you can send them messages using this system - otherwise you need to know their email address.
