I'm an avid, avid, avid Portal fan and I love checking out user created content. I'd like to think I'm pretty good at Portal so hit me with your best shot! However, you should know that I'm only able to play maps that are submitted as a BMZ (Bonus Map Zip) file. So if you want me to review your map you'll need to upload it in that fashion. BMZs are much easier to use and play anyways so it's a better format altogether. It's not terribly hard to convert a map to BMZ, here's the instructional guide: http://developer.valvesoftware.com/wiki/Bonus_Maps
Anyways, enough BMZ propaganda. I'm very excited to be a member of this community and I hope to play your creations soon!

Thanks for the genuine welcome, though, I wish Hober was as hospitable
