High-Level Summary: This is a quick theme change that will show a user's Skype status in their profile field. There are definitely better ways to do this, but this will give you a nice starting point on a better implementation.

This document assumes you have a basic knowledge of themes. You can read more about themes here.

There's a Skype in my Clearspace

The first step is to create a custom text field for your profile and choose a label. Mine was 'Skype':

Now you need to create a theme and overwrite the /template/global/include/profile-macros.ftl. You'll see this section of code at the very bottom of the file:

<#if fieldValue.value?exists>
        ${fieldValue.value?html}
<#elseif fieldValue.values?has_content>
        <#list fieldValue.values as val><#if (val_index != 0)>, </#if>${val?html}</#list>
<#else>
        <@s.text name="profile.na.text" />
</#if>

You'll want to change it to something like this:

<#if fieldValue.value?exists>
     <#if field.name == "Skype">
          <img src="http://mystatus.skype.com/smallclassic/${fieldValue.value?html}"/>
     <#else>
          ${fieldValue.value?html}
     </#if>
<#elseif fieldValue.values?has_content>
     <#list fieldValue.values as val><#if (val_index != 0)>, </#if>${val?html}</#list>
<#else>
     <@s.text name="profile.na.text" />
</#if>

Since name of my field was Skype, that's what I placed in <#if field.name == "Skype">. Yours would look similar, but with your own field name hard-coded in.

When you've saved the template and set your theme, your profile page should now look like this:
