I have to do this every so often just to stimulate more forum traffic...
Sorry about that guys. The problem was both technical and mental.
So my DSL keeps going in and out all this week. Thus, even though I had the strip drawn two days ago, I wasn't able to connect to the Internet to upload it all of Wednesday or Thursday after work. Then I went out last night for a friend's going away party, and returned at about 1:30 and was able to upload the strip then (thankfully--otherwise, I would have had to go to Kinkos).
Unfortunately, at that late hour, I guess I simply neglected to hit the "update my site" button as well, which you have to do if you update the site after the normal auto-update time.
The site is even programmed to page my cell phone if it's not updated by 1:30. But that feature had already activated, so that didn't help me either.
So I woke up this morning and the first thought on my mind was, "Ah crap! I didn't hit the 'Update' button, did I?"
Ugh. But it's all better now.
