You can prevent double posting!!!
Forum posters should click Submit only once.  The forum is very slow to show the post, yet the post is immediately posted, you just don't see it.

I made a forum post this morning.  After I clicked “submit” it took almost a minute for the posting to display.

However while waiting for the display, after about 3 seconds I opened a new BBC window and found the post was already up.  Yet the initial forum window still showed working for another 45+ seconds.

I can easily see how a user would be tempted to click submit a second or third time while waiting for the forum window to update.

Is the slow forum response a SystemSource hosting issue?   It seems that the actual post occurs immediately.

It appears so.  Since we started using secure communications with the server response time seems to be up with the added load.
