Another welcome Kilo. Know it will be tough but please be patient. It's so much better to do lots of research than to do lots of fixin.
I've done both, unfortunately the research was done after the mistakes. You'll be amazed at what can be accomplished in a few yrs if things are done correctly.

May I suggest that you and family/friends do some heavy fishin and determine what is in there and then you will have a better understanding as to a plan.

Figure out what ya want, research heavy and ask any and many ?s.

Good luck and have fun...Bob-O


Do nature a favor, spay/neuter your pets and any weird friends or relatives.
