How to add hyphen or other valid character in Telligent Blog's Web Addresses and display in Sitecore

Question

I have setup two blogs in the Telligent Community site with few posts in them and I have changed the Web Address for them as shown below with examples of Actual and Expected Url in the sitecore side site,

1. Sample WebBlog

   Telligent Blog Web Address setting: Sample-WebBlog

   Sitecore Actual Url: http://www.site.com/Community/2/b/sample_2D00_weblog

   Sitecore Expected Url: **http://www.site.com/Community/Administrators/b/sample-weblog**

   Telligent Side Url: http://localhost/tcdemo/administrators/b/sample-webblog/default.aspx

2. Sitecore Demo Blog

   Telligent Blog Web Address setting: Sitecore-Demo-Blog

   Sitecore Actual Url: http://www.site.com/Community/1/b/sitecore_2D00_demo_2D00_blog

   Sitecore Expected Url: http://www.site.com/Community/Administrators/b/sitecore-demo-blog

   Telligent Side Url: http://localhost/tcdemo/administrators/b/sitecore-demo-blog/default.aspx

So as seen the Url changes the hypen - to _2D00 while in Sitecore and in Telligent it is completely different.

1. So how to add hyphen or other valid url character in the Telligent Blog's Web Addresses (displayed in Sitecore) ?

2. Also How to display the group name instead of Group ID in the url (also check the screenshot from Telligent widget below) ?
