Hi Nightflower, and welcome to the ATS community. For now, you can reply to any thread in any member forum you wish, as well as send & receive
U2U's (messages) to Staff only.
However, once you have achieved 20 posts, you will then be able to start your own threads and additionally send & receive U2U's to and from fellow
ATS members.
Take your time and enjoy. If you have any questions just ask.
