Kim, aside from the specific things mentioned in the huge "What Do You Want" topic (Andrew picks some good ones, doesn't he?) here are a couple things I'd suggest:
• I'd never heard of a Shoutbox before, would a description be appropriate (or is it just me)?
• When posting, there is a button for "Insert Image" and also the "tinypic" link. Why have two? (At first I was afraid of tinypic, I didn't have a clue what it was.) Can the message board size for tinypic be the default?
• I think these similar names cause confusion: Blog Ring & HAF Blog.
• "Crafty Creations" should probably be described as not "jewelry or needlework related"
• What's the difference between "Crafty Creations" and the "General Gallery"?
• Do the colors of the green and purple HAF Hands mean anything?
• What do the different color and number of stars under the poster's name mean?
• Within each category, when you look at the list of topics, there are two columns of icons. Could these have the kind of little descriptions that pop up when you hover your cursor on them, or some other way of describing what they mean?
• A statement at the top of the main forum (home) page, something along the lines of: Welcome to HAF. Originally the Handmade Artists Forum, now including the HAF Shop and the HAF Blog. (Because I think it's confusing to say the Handmade Artists Forum Shop. Could be that quite a bit of the confusion stems from having the word forum in the title: some think HAF means the shop, some think it means the forum.)
BTW, I think Crafted Roots had some wonderful ideas in the "What Do You Want" topic, and I believe volunteered to help with "cleaning and clarity."
Good luck!
