What is the best practices philosphy regarding the hosting of multiple websites. If each website hosted is separate and distinct from the other is it recommended to have a separate database and therefore a separate install for each website or to have a single install of dnn and host the variety of websites within it. Though I am concerned about the users table as everyone is stored there. Or is this no big deal? Just a little confused and some clarification / discussion is appreciated.

Thanks.

Same here. We stay away from multiple portals on the same DNN installation. There are a lot of reasons for this.For example what if one portal want a module that conflicts with a module another portal uses.If you update the core dnn or some modules all portals might need to have their skin updated at the same time.One portal might affect the others in some way (However unlikely but they do run from the same asp.net install). If one get overloaded the others will die with it. What if one portal have to edit the default.css file (Since it contains a lot of specific tags like H1, lu, li and all the rest).

Thanks for all of your input. I began to realize this after I noticed all of the users from different websites stored in the same users table. Now to split my portals up into their own sites.... niiiiiice.
