Hello,
This is MrShlee from #DSDEV for the last few weeks - I've been actively discussing with a number of developers about creating a Central Hub for DS homebrew.
http://www.dev-scene.com is the result and this has been created over the last month by arog, Dovoto & I. This project is still in active development and is not public yet but we want to open it soon.

Please join us and help the Dev-Scene project... Firstly by Improving/updating the Pages about your projects and keeping them updated. Visit http://forum.dev-scene.com and create a phpBB account- then you'll be able to access the wiki :) 

I've created a draft/base for a most of the games/applications and Tech demos, I could remember/find - This page will also allow users to discuss issues/reviews about your software and let you reply back to there comments. If I’m missing an application – look how we’ve set the pages up and make one yourself…. Or make a note of it in the discussions tab.

The Developers portal is dedicated to all developer related things. If you have something you can bring to the page. Any tuts/guides/write-ups/hints would be greatly appreciated :)

Please browse the page and email me any thing I'm missing or correct any mistakes you find.

Thank you,
Ashley "Shlee" Hull
