it doesn't hurt to ask for help from
@Support as that is what they are there for. like if you post a thread and then later think it might be better given a different place - they can move it for you. i think if you only ask once in a while they're fine with honoring requests as long as they can do it and have the time.
personally, i would rather people post replies to existing threads instead of making up new threads with similar topics or titles, but i do also know that not everyone searches for existing threads and titles first and sometimes i don't either...
i also accept that by posting here my posts may be removed or changed by the website owner or the support people or whatever can happen next.
if you want your words to be kept you need to figure out how to archive them yourself. i am glad i did that before for a certain website that has since disappeared.
sometimes the wayback machine can help, but other times it can't.
