Hi Kenw, welcome! Have you been registered to the private DCS members only forum before and is it just the new URL you need or is this your first try to get there as a registered TDS operator? Recently they moved to a new URL so that's why the F5 and menu option to get there from the TDS GUI don't work and will be corrected in the new TDS-4. As DCS support is the one to create the entrance and password for you, if you are new to the forum, you might like to email support@diamondcs.com.au. They're expected back from their holiday break 6 January (Perth time). Excuse me KenW. just found you as an existing user in the other forum. Sorry for not recognizing you immediately! Sent you the new URL in the meantime. Would advice you to remove your email address so openly to avoid email gatherers spamming you.
