Take a look at www.SQLCommunity.com
It's a great new community website, with tips, tricks, articles, scripts, and references to other sites. I am one of the site managers, and we're planning on adding live and online events, as soon as we all get settled in.
One of the things I'll be doing is republishing some of the first articles I ever wrote, for SQL Server Professional Journal, over 10 years ago. I have a series called "Blast From the Past". The first one is up already, and interestingly enough, it is still applicable to SQL Server 2005. Here's a direct link.
Check it out and have fun!
