If you're using an advanced client such as Amethyst that allows you to configure a multitude of relay options, please check out nostr:npub1gcxzte5zlkncx26j68ez60fzkvtkm9e0vrwdcvsjakxf9mu9qewqlfnj5z's recent article on advanced relay configuration. If you still have questions, drop them below and myself or others will try to answer them for you.

If this is too a bit too technical for you, don't worry, you don't have to use Amethyst. For now, you can use Primal, Wherostr, or Voyage on Android.
