@ Koco ...
I think ... I think ... that the fact that you are here, now, and were able to type what you posted means that you have made it through the first hurdle!
If I understand things correctly ... you will still log in/sign on the same way here to this site ... however after the *change*, the site itself will look different and navigating it will be done in a different way (i.e., there will be different things to click in order to do the things you want to do .. like post or add pics, etc.!)
Now .. I may be wrong, but I think that's the way things are supposed to happen! But ... so far, so good! We've all made it this far .. and I think we're good to go!
