At first I wasn't too sure what I was expecting when I joined up. I think having the resources, somewhere I could ask questions if the need arose, and to be able to chat, or even just read comments from people in this field. As with mentors, a wealth of knowledge and insights can be gained by others, so leaving the opportunity open for this to happen is always a good idea :).
It is reassuring that if I have trouble with some aspect, or need some help, I could post it on here, and within days can have helpful responses from others, or even to be pointed in the right direction.
Hope this helps.
