Have you checked out the IDM community space?

Integrated Data Management community space. This space started out as the Data Studio community space by Grant Hutchinson. When I joined the team, I took over management of the space including the move to IDM to be more inclusive of the whole Optim portfolio. If you've never worked with developerWorks spaces, they are kind of cool. Anyone (internal or external) who gets approval can self-publish their own web space using the templates provided by developerWorks.
Anyway, I feel the IDM space needs a commercial because so many people still don't know about it (even people on my own team!), and I must send out the link several times a day. The intended purpose of the space is to try and put in one place links to all the blogs, discussion forums, articles, product documentation, classes, downloads, videos, demos, upcoming events, etc related (mostly) to the Optim portfolio.
Admittedly, the site isn't perfect as I am limited by the dw templates, and I still have work to do to get more of the heritage Optim materials integrated. But most people who discover it do think it's very useful. There is even a place to post messages, but that has not been used thus far. I think using our existing discussion forums is probably the best way to get questions answered anyway. Not sure where the forums are? Well, the links to all the forums are on the space!
As of today, the space is divided in to three tabs: Home, Articles and tutorials, and Downloads. Here is the Home tab:
As you can see in the screenshot above, you can add any of the portlets to your myYahoo or igoogle page (or as an RSS feed) by clicking on the orange plus icon. The screenshot below shows my Yahoo! page with the 'latest news' and forums portlet added.
Here is the downloads tab. It also includes some additional related software such as DB2 Express-C and the Replication Dashboard.
Anyway, I hope you like the space. Let me know if there's anything you want to see added, changed, or removed. And spread the word, please?
