I'm unsure if there will be any security concerns, and furthermore I do not wish to let someone plagarise any part of my code. Is there any way to prevent my site's source code from being viewable?

Good luck charlie with that one. You can get a javascript code. but a lot of guys have programs that download the page. Actually Firefox I believe has a web developer extension that can't be stopped as of yet. It's a game that forever keeps going to the next level.

Yeah like he said. I know that sometimes if I like a website I will check out their code to get an idea of what they did. I never steal their site content but I do look at it.

Won't deny that. You would be hard pressed to avoid that. I can even see Walmart code.

But don't fret you can insert a code I believe that doesn't allow them to copy so this is a good deterent. Not full proof of course but it helps!
