how long between hitting "publish" and actual publication?

They should have a temporary site where "un-filtered" new instructables can be viewed. That being said, here's mine that isn't published yet (given I did publish it at 6 AM on a Sunday, only 6 hours ago.

the instructables team have to review it, so if you have a very long instructable it will probably take longer than a very short one

It would be nice to know a little about the filter. It took my first instructible 4 days to show up in the recent-instructables list. There have been so many instructables in the last few days that mine was on page seven by the time it showed up. I suspect that this happened because I changed the license from the default to the less restrictive Attribution license. Assuming this was the reason, and that I had known, I would have kept the default license. The whole point of changing the license was to make it more likely that people would spread the idea around. But a page one appearance achieves that goal far better than a slightly less restrictive license.

I have troubles while trying to publish my first instructable.
The thing is, I wrote the I'ble, hit the publish button, it gave me the "share it with your friends" option, and it even said that while the publication process finished, there was an active link. Clicked it and everything was on it's place.
However, after checking the status 2 days later, I found that there was no Instructable at all. I wrote the given link, but it said that the author (me) had deleted it. I did not such thing. I logged in, but there was nothing to show, not even on the unpublished tab.
So i re-did it again. Published and stuff. Same thing happened. That got me really mad. But since I was logged in, I just hit the "edit" button that appears only when you're the author of that I'ble. And to my great relief, every step, every image, the whole I'ble was still there. So I hit "publish". The I'ble is still there, but, how ca I be sure that it won't get "deleted by the author" (without me doing it, of course)?.
I didn't get a notification saying that it was an illegal I'ble, or something like that, it just got deleted.
I'm using Firefox 3, and it might be helpful to add that even as I check the "remember me" box, I have to log in every time I close Firefox, even while it is configured to show all the open tabs at the time of closing the program.
I would really appreciate any information hat might help me. Is it the browser I'm using? What else could it be? How could I stop this from happening again?
Thanks beforehand.
By the way, heres the newest link: Click me to see if I'm still alive.

I have had some appear in the Recent listings after only ten to twenty minutes. Oddly, I posted three on Saturday. The first one has not yet appeared after more than a day and a half. The other two appeared almost immediately. My experience in the past is that they all usually appear sooner or later. But, an Instructable posted several days ago that appears tomorrow will be listed with other Instructables from the same day it was posted, which makes it harder for viewers to find in the Recent pages.

. Depends. . If it doesn't get caught in a filter, it appears almost immediately. . If it gets caught in a filter, it will have to be approved by a human. That can take from a few hours to a few days. Weekends and holidays seem to slow down the approval process.

I posted an instructable at around 8:30 January 17th 2009, and its 10:15 on the 18th, and it stil isnt up, so its taken me about 14 hours and it still isnt up.

They usually come up really quick but sometimes it will take up to 24 hours.
