Hi there Sandy and welcome from me as well.

I'm another oldie with MS, and by that I mean both meanings. I'm on the wrong side of fifty and was diagnosed 31 years ago but so far I've not been down the Tysabri path. We do however have many members who have, and I'm sure they'll be more than willing to share their experiences with you.

I see you have the relevant links, so hopefully I'll get to know you a little better in the forums.
