First Question;I think you have an extra LASTN_HEAD<= lying around somewhere in the overrides. Check to make sure. You should have:
LASTN_HEAD<=
some code.....
<=LASTN_HEAD
Also, you can change that to GLOBAL_HEAD instead, that way it will work for everything (friends, calendar, etc.). That will eliminate a need for FRIENDS_HEAD, etc.
Second Question;To get rid of the top table (there's a pinned thread here for that), use the following (OUTSIDE the GLOBAL_HEAD, this is separate):
And this inside GLOBAL_HEAD in the style tags somewhere:
Third Question;I'm not quite sure you can get rid of the whole thing, but I know this will hide the links:
Obviously, that should go in between the <style> tags in your code. If that doesn't take out the entire box at the bottom, I don't think you can get rid of it.
