If you're trying to use the HTML code (<a href> etc.) to put a hyperlink in your skin, this is impossible as Messenger does not support the HTML standards, but rather uses a mix of XML and something like CSS.
The only way (that I know of) to put a link in a skin is to put
<AboutUrl>http://www.example.com/</AboutUrl> in your SkinInfo, inside the
<Information> tags. This will add a link to the website of your choice in the Messenger Skin menu located in the Plus! dropdown in your contact list.
To add this link to the UIFiles, you will need to create a new element or replace the content of an existing one (make sure it's nothing important, though, like the Send button
). For example, with the 947 UIFiles (the login screen):
Find "idForgotPasswordLink" (without the quotes) in the 947
definition and you will find a
<urlelement> for the Forgot Password link. The element
must be a urlelement, otherwise it may not work. Change the cmdid to 7461, this is the ID Plus! uses to open the current skin's AboutUrl. You can change the text shown on this link to whatever you want, by searching for the id of the element in the respective window's style file.
Hope this helps
