By now you are likely pretty familiar with FanPosts, but I wanted to also point you in the direction of FanShots. While FanPosts are for article length posts with fully developed thoughts, FanShots are quick hit links or images. Basically if you want to share something with your fellow Celtics fans and don't have time to develop a full article about it, just use a FanShot.
You can post links to articles, you can post quotes, you can share images or videos that you find funny or interesting, and you can post a fun list. See examples of each here.
I have the ability to put these on the front page as well. So if you see or hear of a trade rumor, share it with us and it might show up on the front page.
One last (pretty exciting) note: They have now tweaked the software to make tweets show up in FanShot links. Just find the link to an individual tweet (usually shows up as the time stamp) and post it into a link FanShot and the software does the rest. See example here.
Lastly, you can find all the FanShots in a better organized page here.
So remember, when you see something that interests you, FanShot it! Have fun.
