HI there -
We are experiencing an issue with some profiles after the site update last night, but we are looking into it, and I'm sorry this is affecting you.
Most of what you use your profile for can be found on your home page, but your communities can't. If you go to your Watch List from your home page, you can see your Communities, but not user groups - http://www.medhelp.org/watches/list_discussions/874521?personal_page_id=861539
(Click/tap on the Communities tab at the top - you'll see Discussions, Expert Forums, Communities and User Journals).
You can go here to search User Groups - http://www.medhelp.org/user_groups/list
If you need help finding one, please send me a PM, and I'll be happy to help.
