I can't get the paper clip to work for me, I think because of my browser/pop up protections. I use Firefox as a browser and my system is pretty well locked down in terms of being extra cautious, isn't so easy or fun for me to browse the internet as you might want, but I don't get any serious consequences. Among other things, this system has never had Java installed and that will cause weird problems here and there on older sites particularly.
So for me it's scroll down and manage attachments.
I actually rather like the thumbnail attachments. Wish there was an easier way to tab/navigate through them, but most boards don't deal with pictures at all because of bad human behavior, so I'm pretty thankful that we have them at all.
