Some email from the ODP gets inadvertantly caught by ISPs spam filters.
You should have received an email to say that you had applied, and that you must reply to that email for the application to be put into the application queue.
Did you at least get that email and reply to it?
If you answer "no" to either, or both, of those questions then the ODP has never received your application!
If you answer "yes" to both questions, then the application was probably received at the ODP. You should then have received an email confirming that the application was received. If this email is missing, either your confirmation [/i]email wasn't received by the ODP to push your application into the queue, or the confirmation email from the ODP back to you was eaten by your ISP.
For an appliaction that does make it into the queue, there are then several possible outcomes:
If you haven't received any other mail since then, then either your application is still in the queue awaiting review, or it has been rejected. I believe that most Meta editors send a standard rejection form email, but often add a few application-specific notes to the end. Your ISP may have blocked that email.
It is also possible that you were accepted but your ISP dumped the acceptance mail. A small number of accepted editors never log in to their account once accepted.
There is another possibility that could have occurred in all the server changes occurring in recent weeks: that a glitch or bug simply ate the application for breakfast. Unlikely but not impossible.
Post details of editor name chosen, and category applied for, and someone with access might be able to check it for you.
When/if you get confirmation that previous applications are all dealt with, then feel free to apply again. Keep copies of all the forms you fill in (cut and paste to text editor).
Good Luck!
