Currently we are using iJoomla magazine for our articles.
We are considering using K2. However our main concern is that we NEED to keep the same URLs.
Will this be possible? Or do we need to make a script in order to keep the same URLs if we consider
moving to K2?

Also, we are going to have a community in our site. We may use Jom Social or Community Builder.
Will K2 work well with this?

Any info, advice or suggestion on these concerns is greatly appreciated and needed.

thanks
