JLR -- you have not committed a faux pas by posting on my timeline, but the timeline feature of the forum is not particularly well integrated into the main forum part, and may not show up using the search function.
It is generally best to post in the "General Discussion" forum, unless you are aware of a specific subforum that is directly on point. But posting in the General Discussion forum is always safe because I can easily move threads to a more appropriate place if needed.
The "timeline" feature is generally best used for posting things about yourself that don't really fit into another subject.
