Any help you can provide, is always greatly appreciated. I’ve started making a section on the wiki around developing for liquibase (http://liquibase.org/development/home) but have not made a lot of progress so far. If you think of documentation that you think will help, let me know of add to it if you can.
Basically, I have SVN commit access open to anyone with a liquibase.jira.com username/password. I look through each commit to make sure you aren’t breaking something you didn’t know about, and will modify and/or roll them back if necessary. Starting with bugs/feature fixing is usually the best way to get acquainted with the source. You can see what is open on liquibase.jira.com, or find things that you want done.
I think it is best to create a new jira issue for each feature or bug prior to working on it, so we can track them in releases better etc. If you want discussion around a particular feature, I think it is best do do on the issue itself. If you have general “should we do this” or other general developer questions, you can use the liquibase.org/forum developer forum.
