Thanks Jess, I had already found all that stuff.
My main problem with the site is how slow it is and how difficult it is to find posts in the online network. For example, I just got a message in my inbox saying that you had commented on my post and to 'click here' to see the post. That link does not work at all. So I have to search for the post through my posts on my profile page - that is the easiest way for me to find those posts. However if I comment on someone elses post and then I get another message to say that the original person has replied - I have to wade through all the posts to try and find the one that I made a comment on...very frustrating.
I have no doubt you will get these things all ironed out, it just makes it hard for newbies.
