Well, after the downtime from last week (it didn't actually last very long), ZXBN is back up-n-running, and has had a few additions to the setup. Aside from some new buttons available for linking (you can see one on the left), there are now 3 supported sizes for buttons-and-banners. The standard banner (470x60) is still available, of coz, but now you can create banners of size 100x100, and buttons of 88x31. Looks like I may have to redo my buttons (they're a little "off").
Anyway, the members page has been split up into "size" categories, and each list is continuing to grow rapidly. If your site's not listed, go get designing!
