Actually, GrannyBerg has only posted to or cheered existing threads, including this one and a few others.
Many forums promote a one-question-per-thread policy -- if someone reading a thread has a question of their own rather than a reply or comment about the original question of the thread, the person is encouraged (or, in some forums, required) to start his or her own thread. However, if one is not able to locate the "Ask a question" button, then one is not able to start one's own thread here. One can only post off-topic questions to existing threads - which, arguably, does not demonstrate knowing "how to post questions," at all.
It is fortunate for that hapless forum user if posting a new question as a reply to an unrelated one does not violate the norms here, and still stands a chance of getting answered anyway (especially since the Ask a Question buttons are buried so far down in the navigation and hard to find unless you already know where they are). It's definitely NOT a given on some other forums.
