>Thank you. I had not checked the chatter forum, so I did not see that option. I just checked it, and now I see it.

Keep in mind, that in such situation, assuming you cannot find the desired category, there is always a Chatter category in each forum to post your new message in. The most important thing is to create a new thread. Cross posting topics in the same thread diminishes the capability to get support and makes important content to be lost in space.
