Hey Matty. There is a thread in the DW section called Inside The TARDIS. Thats where most of the general chit chat goes if it is relevent to the series since it came back in 2005, but if you want to chat about the classic series then there is a forum for that too. If its audios, or dvds, or merchandise or whatever, they all have homes too. Inside The TARDIS is probably your best bet though. Thats where everyone else has their DW chat on that isnt related to the upcoming stuff
Hope that helps
