Karen, Welcome to APF. Glad to see you here
Now re: hosting, those choices are all fine places to host, BUT .... give it a week or so to decide. We are preparing to launch something pretty big as of new year, It's VERY VERY hush hush right now but will be very very cool. Jay and I have been discussing it and preparing it for a while now, announcement will be made the first week of january for sure. Just wait a bit.
