This is as easy as I could get it.
To add a friend, insert this two lines before it says container.innerHTML:
//Friend #
//ID -
var id#='idnumber'
//name -
var name#='name'
# = The number of the friend. For example, if he is the 7th friend in the script (after //Friend 6) then # will be 7. This goes after //Friend, id, and name.
idnumber = The digits at the end of the user's home page url
name = Your chosen name (i.e. Bort)
Also insert this one line before the last line of code:
'<td><img src="' + avatar + id# + '" width="75" height="75">' +
'<br><a href="' +
friendlink + id# + '">' + name# + '</a></td>' +
# = Same as above
I know it's kinda complicated, but I'll try to look for an easier way. If you have any questions, ask them.
