First off, congrats on your success ! It also sounds like you are getting very close with WILDing, so just keep practicing.

You weren't remembering dreams before, because you weren't actively trying to remember them. Joining a dreaming website and simply wanting to remember your dreams can help boost your recall. Dreaming and everything related to it is all in your mind. If you want to remember your dreams, practice dreaming, and keep your mind on dreaming, your recall will improve off of those things alone. You can further enhance recall by keeping up with a Dream Journal, performing mantras, etc. Again, congrats on your success and keep up the good work !
