The Oilers forum has some GDT templates you can mooch - some decent post tags, etc. There's also an FAQ somewhere on hfboards that lists all the tags you can use.
I'll probably end up doing the GDT for the Avalanche on Sunday since no one has grabbed it yet. If you quote my GDT post, you'll get a good overview of some of the tags that are available, how to link to pictures, etc.
Go for it! Need some new blood on the GDT front!
It's too bad you can't "quote" after a thread has been closed. That would be helpful for looking at how people format.
For example I have no idea how the tables are created. They seem like too much work.
