Non-registered interface
Welcome, Gerald, couldn't agree with you more, this interface leaves much to be desired, for registered and un-registered alike.
At this point, it is not going to get better anytime soon.
I'll post some hints on the front page, but basically, you want to ignore the editor at the bottom of a thread you've opened. Always use the "reply" button at the lower right hand side of the post you want to reply to. To start a new thread, use the "start a new topic" button at the top left of the page.
We've had discussions about the lack of obvious fields in the editor (like name and the anti-bot code) and we are working on a solution.
Thanks for your input.
