Finding your way around the forum will get easy in no time. You can get into the main menu several different ways. You can click on the big Neurotalk logo and it'll take you to the main menu, or I usually use the 'forum jump' down towards the bottom of the page. When you're in the main menu, scroll down a ways and you'll get to the alphabetical list of health related topics. Or just pop in any of the forums listed and start a new thread (top center, like you did here) or post a response to a thread by hitting 'reply'.
Just holler if you have any more Q's

You'll be hooked in no time
