Hi Jen,
Just saw your post, I went through the same and contact Alan Kelly (the owner) about that and it was a "time out" issue, when we takes more than 20 minutes logged in but typing our profile the site log us out just like banking websites do for security, so if you hit the back button you can go back to the page where you were writting do a copy and past to a world document and log in back in w2meet again past your profile or forum whatever and hit subimit and will work.
Alan is looking for a better way to sort that but it is also in our own benefit in case if we leave our desk while log in and someone try to use.. all that..
I hope this help, please do come back to the site it is getting very busy and more opportunities to promote your business.
Have a great weekend.
