I'm excited about 2008. And I'm really looking forward to the new layout(s?) for IJ. If it could be white as a background, that would be even better than the grey it is now! One of the reasons why I stay using the default view in IJ is because the top image is very small. It means I don't have to scroll down as much every time I view a page, and I like that. Oh, but I can't wait to see what your chosen user comes up with.
One improvement I'd like to see IJ add in the future would be the ability to preview icons in comments, not just in new posts. This is a feature that GJ has (LJ doesn't - at least, not in a convenient format) and I loved it. I miss it.
The Private Messages feature is badass. Don't ever stop.
I can't think of anything else I need from this site. It's been so, so great -- the open arms to me and my RP group, the clear dedication you have to the site, the fact that you talk to us about what's going on... It's a far cry from what I've come to expect... and I'm afraid IJ has just ruined me for any other journaling site.
So thank you. Thank you very much. And best of luck for 2008!
