Im up for seeing a Do It Yourself section as im currently writing a set of instructions on waterfall construction because there is simply not much information avaliable on it. If there was a Do It Yourself section it would be easy to post my info for people (as im a little confused on where to post the finished product?) lol.
Maybe make it general, as i've read loads of Do It Yourself forums on enclousres and you can often take ideas from different people, or maybe simply don't think of something if you are specifically looking for a certain species.
That's my two cents lol.
