1. Search is automatically AND, for example “online noob” means “online” AND “noob”, and only returns this topic.
2. Tick “Notify me of follow-up replies via email” when you submit a post, but you know that now 🙂
3. You cannot see who is online.
4. You should not ask a question over and over again, but just wait for an answer :). See the support policy: “Our support hours are Monday to Friday, 09:00 to 18:00 (UK Time). We guarantee an answer within 24 hours to all Support Topic Monday to Friday and within 48 hours during weekends. This doesn’t mean all solutions will be provided within 24 or 48 hrs. For more advanced or technical queries it may as well take longer.”
5. Questions get answered in order anyway by any of us who are online, so you really get the same result.
