Looking for some expert advice from you guys, I am going to be attempting to port an L2U solution over to Razor and change the queries... I have a query that I'd like to get your advice on how you would attempt to write it.

                var u = MyUmbracoDataContext.Instance;


                // Get the lastest 30 posts from this user
                var posts = (from p in u.ForumPosts
                             where p.ForumPostOwnedBy == CurrentMember.MemberId
                             select p.ParentNodeId).Distinct().Take(30);

                // Now get topics where the user has posted
                var maintopics = from t in u.ForumTopics
                                  where posts.Contains(t.Id)
                                  orderby t.ForumTopicLastPost descending
                                  select t;

                // Now bind
                rptTopicList.DataSource = maintopics;
                rptTopicList.DataBind();
