Anyone use e107 CMS

Is anyone familliar with the e107 CMS or have it on a team website? I really like it so far. I was wondering what is the best way and what is the easiest way to customize it? Also, how do you install Coppemine into it?

Please don’t turn this into a CMS are good/bad debate.

Just on the off chance that you haven’t seen it, this is probably the best place to ask:

I was mainly just wondering if anyone on here (teams) use it and what they did with it.
