I've just registered and so i'm playing around trying to get to grips with what you've put online. I have couple of annoyances already, which i expect will be shared by many new members as the they sign up.
1. Immediately after registering i was taken to a login page, with no explanation to say why i was there, or even if my registration was successful (no thank you message).
2. After logging in, i was taken to a page displaying my registration information in a form, presumably to see if i wanted to change anything? But If i've just registered, then logged in, then chances are that i would like to see your member content - not a re-display of the stuff i've already typed in.
3. Now that i've logged in and have posted a couple of items to the community forums, i've noticed that my username is displayed next to my posts, instead of my name, which is undesirable (other members seem to have their name displayed, which is better). So i've tried to find the page with my registration info on again....but can i find it? I assumed i should click on 'logged in XXXX' in the top right corner, but although this is a link, it doesn't go anywhere.
Anyway, these are just a few little problems i've experienced so far, i hope they're not too critical i just thought they were worth pointing out as improvements that could improve the user experience.
