Telligent's Community Server | The company I work for is wanting to add blog functionality to our website and they were looking to spend an awful amount of money to have some crap being built on top of a CMS they purchased (sitecore). I pointed them to Telligent's Community Server and we had a sales like meeting today to get the Marketing folks on board. 
My question is if anyone has had issues working with Community Server, skinning it and extending it?  

I wanted to explain a bit why I am thinking Community Server, the company is wanting multiple blogs with multiple authors. I want to be out of the admin part of this as much as possible and didn't think there were too many engines that having multiple blogs didn't mean db work. I also like the other functionality that Community Server provides and think the company will find it useful, particularly the media section as right now we have some really shotty way of dealing with whitepapers and stuff.


edit: We are actually using the Sitecore blog module for a single blog on our intranet (which is actually what the CMS is serving). Some reasoning for why I don't like it for our public site are they are on different servers, it doesn't support multiple authors, there is no built in syndication, it is a little flimsy feeling to me from looking at the source and I personally think the other features of Community Server make its price tag worth it.


another edit: Need to stick to .net software that run on sql server in my company's case, but I don't mind seeing recommendations for others. ExpressionEngine looks promising, will try it out on my personal box.
