Xenon; sorry if its already been posted, a user on my forums made three posts with the exact same content and it processed it as three different posts. (so the user has three posts saying "thank you")

hmm, that posts should filtered out by the dupe check already

are you sure you don't have another hack installed?

I don't think there are any conflicts, I do have the hack installed which marks the thread as old after xx days, but the thread the posts were made in, is recent.

the user said, he was stuck on the page for a while.

I just tried to duplicate the problem, but can't seem to, will see if it happens again and post back.

Would you mind cleary addressing the quick reply issue? I just did a fresh install of this hack on a fresh 3.5.3 board, and the quick reply still doesn't refresh the page automatically.

Paul's fix apparently doesn't work with your new release either.

Erm?
there is no quick reply issue in the newest version.
there is no refresh after a QR if you have ajax enabled.

I just installed today and I as well have to refresh before it merges the posts.

Also how can i exclude this form 2 forums. I tried,
But that just made a duplicate messaage turn up evrytime i posted.

on ajax it will look like two posts and will be merged afterwards, that's why the tilte of the ajax' post is 'Doublepost will be merged'

as for your code, there are two mistaked:

it's in_array, not is_array

and you should use $threadinfo[forumid] instead of the $globals one

agreed
On a fresh install of vB 3.5.3
after a post, when you quick reply it shows as two posts
then you have to REFRESH for it to merge

yep, that is working as designed

the post is already merged, but with the new AJAX features of 3.5.0 that's the only possible way without really much hacking into the files as well

I am using this in Additional Condition input field and it is still not bypassing your hack in the apropriate forums.
