If you're hosting your open source project at java.net, you might be annoyed by the fact that you can't disable the forums or issue tracker. The forums pretty much suck, mainly because there's no "remember me" on the site and it's a pain to click 3 times just to answer someone's question. They also don't have the ability to quote a previous message. In addition to the less-than-adequate forums, the issue tracker doesn't hold a candle to JIRA.
For the longest time, I've been wanting to remove both the "Discussion forums" and "Project issues" links from the AppFuse homepage. I asked the java.net folks, and they didn't have a solution. Finally, I thought of one on my own.
