Some doubts about patching

[Jose Antonio <srarcos@gmail.com>]

Hi all,

I've been checking the website of "Release-critical bugs status" at http://bugs.debian.org/release-critical/debian/all.html. And I have several questions:

* I have installed Wheezy but not Sid nor Squeeze: Can I filter the bugs to find only those corresponding to Wheezy?

* Imagine that I start to create a patch: How do I know that there is any maintainer developping a patch for the same bug?

* If I create a bug: Do I have to sign it before sending it to the DM or DD that maintain the package? And if so, my key is not in keyring.debian.org, is there a problem?
