Hi Ian
Well, you've registered and made your first post, so that's a good start!
Seriously, feel free to use this forum in any way you wish to help further your writing interests. As mentioned, you can post questions about any aspect of writing, seek out potential collaborators or expert interviewees, post short samples of your work for feedback, and much more.
Just a couple of things to bear in mind in order to get the most from the forum. First of all, choose the board which is most appropriate for your posting. If you want feedback on your writing, post your message on the Review My Work board, for example. And second, if you are starting a new topic (or 'thread' in forum-speak), click first on the New Topic button at the top of the board concerned.
Once again, thank you for your interest in registering on this forum. I know it's a bit quiet at the moment, but we've literally only been going for a day or two. Very soon I hope the forum will be heaving with interesting messages, so don't forget to bookmark the page now and return to it often!
Nick
