I had some dissapointments with the hosting service I was using for SlapDev.com and with the Community Server app that I was using for it. I'm not sure if my problems were all to do with the hosting service, all to do with Community Server, or somewhere in between.
All my sites are back on http://discountasp.net 's servers. I am very happy with there hosting service, especially after moving away and then having to move back. I definately recommend them to others.
Now for Community Server; I guess I'll have to do more testing befor I launch a site with it again.
