I've accessed this forum with Safari, Firefox, Chrome and get the same dark text on dark background issue on all. Not sure which div needs a background, but it renders the forum posts very hard to read. I've attempted to attach a screenshot, but I'm not sure that works, either.

Thanks! Could be great to get a screenshot (attachments are enabled) or at least a link. We just updated Agora, some problems might be expected.

Seems to be fixed now, looks like you've chosen a new skin. Thanks for jumping on that!
I tried to attach a shot yesterday. It would upload, but I couldn't see how to add it to the post. Might want to look at the formatting of that attachment uploading shadowbox. It's so wide you have to scroll very far right to see the little checkmark that actually puts it in the post.
I did figure out how to attach these shots of the too-wide shadowbox.
Thanks again!
