The Skype TX client on TalkShow can add contacts, but it does not share contact info. This can be problematic if the setting "Allow all incoming calls" is unchecked.
From the TalkShow, open up Internet Explorer and navigate to web.skype.com. After signing in, use the "Search Skype" field to find contacts. This works just like the consumer desktop version of Skype does. Skype Contact info can be shared, and invitations to share Skype Contact info can be accepted.
