You Do Not Have Sufficient Permission

Yes, I had to remember to copy and paste before on PA and here. And it was random. I had such a heard time replying to a private message on PA and then replying to a forum post here earlier this year. I forgot about the copy backup. But it was late and I wanted to post before going to bed, so it really pissed me off that I had wasted my sleep time for nothing.

I copy this now before I post because you never know when it will work and when it won’t.

Don't take it personally - I'm an admin and have got this message on and off for years. I think if you take too long to submit a post it can do this, though at other times it seems pretty random. I've learned to copy my posts before hitting submit just in case, then I can quickly paste it all back if the forum software has a hissy fit. 

I just spent half an hour typing up a forum topic, typing quotes from the internet and adding my comments. And what happened when I tried to post it? I got an access denied message. And when I went back, all I had typed was gone.
