Thought I would get around to putting my profile on here.
Im 30yrs (for two more weeks) I live in Wiltshire with my DH and three boys. DS1 aged 10, DS2 aged 7 and DS3 5 months.
Posting piccy of my boys...DS3 doesn't look so startled these days
Hopefully this will work.
If you look at the top of the screen where it says home, talk etc the last option is to log in. It should tell you there if you are already logged in or not.
If you are, and still can't post pic then I am not sure what problem is. You could try contacting mumsnet about it or if you want, I am happy to post you a new profile if you send me the pic and what text you want on.
