What must I do to get my questions approved? I can't even post comments and don't know how to message mods

The moderators here are all volunteers and approve questions from new users as we have time. Sometimes the queue gets backed up and it can take awhile for your question to be approved. This system is in place to prevent spam and hundreds of "write my script" type questions that would flood the site otherwise.

It looks like your question was approved at some point so you should be good to go. Once you participate in the site enough by asking good questions, answering and commenting you'll built up enough "karma" to be able to post without being moderated.

Also, you can post in the Help Room at any time without waiting in the queue since that area isn't moderated.
