I'm Rob Marshall, a consultant who specialises in the Microsoft System Center Configuration Manager product. I like to share, i do so by blogging and helping out when I can in the MS SMS newsgroups and participating in the ConfigMgr MVP program.
I was awarded and joined the program in 2009. It'd be an understatement to say it has to be one of the best experiences an IT engineer can have, if they really enjoy specialising in a product.
My biggest weapon for troubleshooting is, my formidable knowledge, no, only joking, you, the community. I find if I cannot answer a question, then I can usually find the answer from using Bing\Google, pouring over the documentation, and if that doesn't work, tinkering in mine or someone elses virtual lab.
The blogs pretty much about ConfigMgr, but it is also a platform for me to express my random urges to display something I've stumbled across, and that I imagine would entertain you or what not as equally as it did me.
As you probably already know, ConfigMgr 2011 (v.Next) uses SQL Replication to pass data between sites ...
I've been troubleshooting SQL 2008 Replication, and found a few interesting links that might help grow out your skills in this area if you're not already above novice-level :-)
Here is SQL Server Replication exposed on MSDN in all its glory: http://msdn.microsoft.com/en-us/library/ms151198.aspx
Here are a collection of links on troubleshooting from MSDN:

Alexander Chigrik has a write up on SQL Replication troubleshooting ... http://www.databasejournal.com/sqletc/article.php/1468971/Troubleshooting-Replication-Problems.htm - Not sure how appropriate this to the way ConfigMgr expects SQL replication to be configured so be careful what you change, and only use this guide by Alexander to identify existing faults rather than using it to define a standard group of settings for SQL (read the article, you'll understand)
