Glad to see a thread like this.
I'm currently relearning German after taking it in highschool. I thought I had forgotten most of what I had learned with the exception of a few words, phrases, alphabet and numbers, and a couple of the grammatical rules. But so much came flooding back once I started it back up.
I'm also learning Spanish. At first I thought German was easier, now I'm believing that German isn't easier, just easier to pronounce (I have trouble rolling my r's)
The system I'm using seems to be working well for me. I've finished all the German lessons and now practice reading stuff online. A little over half through with Spanish.
I'm very jealous of my best friend's brother. That guy just has a gift for picking up languages. And he's mostly self-tought He's currently fluent in German and Japanese, and at least conversational in Hmong, Romanian, and one other that escapes me. Italian, I think.
