Can I limit access to a post (stickie) to the thread OP?

[creativeforge]

I'm trying to see if I can limit access to a stickie post to only its original creator?

That stickie is going to continue receiving content from the OP, relating to updates of a software, but locked to further replies by anyone else.

I will need to move the rest of the posts from that stickie to a regular thread.

How could I achieve this?

Thanks!

So there is a time-limit on deleting my own thread? My question is now irrelevant so I wanted to free space.
