Hi dbashyal!
Welcome to MODx! You have made a good choice

- but am hopelessly biased though

.
Though "easy" is relative, you will find MODx very flexible. It will do what you tell it to do and not box you into some corner about "how you should do stuff". Your designers are going to absolutely love it! MODx will not place any restrictions on their designs. Your developers will love it too and find it easy to extend; the API’s great and if they know their PHP, MODx will happily eat it and return the results..
One of our "weaker" points is documentation

. It is not missing per se...it is just, well, here and there in some cases. Don’t let this put you off at all. This is something being worked on but you will find most answers here on the forums and in the wiki (official and public). Below are some great sites to start you off.
One of MODx greatest assets is its community; it is vibrant and very helpful. Feel free to post away..though google and the search function are also your best friends especially if you know what you are looking for or at least have an idea of what it is you want...If you are a twitter person, MODx is also on
twitter.
Which version are you testing btw?
