I was confused too when I saw this topic!!!
Alector, double posting usually occurs if you click the
Add Reply button more than once. Sometimes it may be a bit slow to change to the next page, so you just need to give it a moment.
We do have a flood control on to prevent that... but it doesn't seem to work sometimes (looks like I have some testing to do).
In the meantime I just deleted the double post... I make sure I keep an eye out for those things!
