Adding posts to a Pack Records thread

Hey! I was wondering if there was any way I could add posts to the Pack Records thread for Duskfire Glacier that Wintersbane/Torvi originally posted. We have a bunch of stuff in development (new subterritories, new policies, general information etc.) that I would like potential joiners to be able to access. 

I can make a new Duskfire Glacier thread in the Pack Records forum if need be, but my preference would be to just add posts to the current one. It does also give me the option to edit Wintersbane's post, but I'd really like to preserve it as-is for posterity's sake.
