The only thing you can really do is find the thread for your PUBNAT number, and just keep reading that for any updates.
Through these forums, I was able to read what the FEBOTS applicants have found out, such as: when the panels meet to pick people, when we might receive our emails, and when the first people received their PEPC invites.
You only need to worry when everyone has received an invite except you! (I got mine at the end of the last day that invites were emailed, so I was nervous.)
