made one reply and 4 posted

Don't know what happen but after submitting a reply it created 4 of them. Not sure but site was very slow in loading when this happen.

There's two things that happen when you hit the reply button, first the post is added to the database and the you're redirected to the post. When it hangs if it hangs on the part where it's already been added to the database and then you hit the submit button again you'll get a double post.

It happens, don't worry about it. Just hit the report button so it can be removed.

I think on some computers/software etc..if you submit it and then hit the BACK button on your browser it can sometimes re-submit it again.

I had that happen once when buying something. I was pissed to see my card whacked twice! A phone call straightened that one out easily enough.

Did I mention I hate computers?

Oh yeah, at least once I think
