Another little TIP. based on a question by trystanc on this forum, he asked about the thread safety of singleton patterns. after a bit of research, i came up with a minor change that addresses the failure in the TBH implementation. anyway, here's a link to the original thread, as well as my code changes below:

http://p2p.wrox.com/topic.asp?TOPIC_ID=65461

here's how my ForumsProvider (DAL\Provider\ForumsProvider.cs) 'intro' looks now:

namespace MB.TheBeerHouse.DAL
{
    public abstract class ForumsProvider : DataAccess
    {
        static private readonly ForumsProvider _instance = (ForumsProvider)Activator.CreateInstance(
                    Type.GetType(Globals.Settings.Forums.ProviderType) );

        static ForumsProvider() { }

        static public ForumsProvider Instance
        {
            get
            {
                return _instance;
            }
        }

        public ForumsProvider()
        {
            this.ConnectionString = Globals.Settings.Forums.ConnectionString;
            this.EnableCaching = Globals.Settings.Forums.EnableCaching;
            this.CacheDuration = Globals.Settings.Forums.CacheDuration;
        }
        // other code below unchanged

hope this makes sense.
