How to replace some text in the user cp fields ?

[Venusian]

I am creating a gaming community and 

I thought it would be a good idea to make users show off there Steam,Origin,Psn Or Xbox Live accounts ?

So I dont really want Contact Details (skype,icq,google,yahoo,aim)

See this image (this is before the person replaced the text) : Before
See this image (this is after    the person replaced the text) : After


As you can see in the second Image the person has replaced "Additional Contact Info" with "SocialNetworking Sites"

I want to  Replace Addition Contact Info    With    Gaming Details
and Also instead of (skype,icq,google etc) I want to have (steam,origin,psn,xbox etc)
