 There are a number of ways to get involved with the development of jQuery core. Even if you've never contributed code to an Open Source project before, we're always looking for help identifying bugs, writing and reducing test cases and documentation.

 This is the best way to contribute to jQuery core. Please read through the full guide detailing [How to Report Bugs](#How-to-Report-Bugs).
 
 ## Discussion
 
 ### Forum and IRC
 
-The jQuery core development team frequently tracks posts on the [http://forum.jquery.com/developing-jquery-core jQuery Development Forum]. If you have longer posts or questions please feel free to post them there. If you think you've found a bug please [file it in the bug tracker](#How-to-Report-Bugs).

 Many bugs reported to our bug tracker are actually bugs in user code, not in jQuery code. Keep in mind that just because your code throws an error and the console points to a line number inside of jQuery, this does *not* mean the bug is a jQuery bug; more often than not, these errors result from providing incorrect arguments when calling a jQuery function.
 
-If you are new to jQuery, it is usually a much better idea to ask for help first in the [http://forum.jquery.com/using-jquery Using jQuery Forum] or the [http://webchat.freenode.net/?channels=%23jquery jQuery IRC channel]. You will get much quicker support, and you will help avoid tying up the jQuery team with invalid bug reports. These same resources can also be useful if you want to confirm that your bug is indeed a bug in jQuery before filing any tickets.

 ### Reduce, reduce, reduce!
 
-When you are experiencing a problem, the most useful thing you can possibly do is to [http://webkit.org/quality/reduction.html reduce your code] to the bare minimum required to reproduce the issue. This makes it *much* easier to isolate and fix the offending code. Bugs that are reported without reduced test cases take on average 9001% longer to fix than bugs that are submitted with them, so you really should try to do this if at all possible.
