Invalid version number & enable synch

Hi,

I have two issues:

1: During my deployment setup and initial tests I accidentally created an artifact with commit id instead of a meaningful version number (stupid...). Is there any chance that I can remove that artifact from the release repository? Since it was my first release I assume auto synch with central was not enable yet? This is the bad artifact: https://oss.sonatype.org/content/repositories/releases/com/connctd/tracing/stackdriver/stackdriver-opentracing/5407f4e/

2: Could you please enable the auto synch so that artifacts will be synched with central? At least it was mentioned over here http://central.sonatype.org/pages/releasing-the-deployment.html that I have to ask for it if it is the first release

Thanks!
