do macros and other downloads for IJ disappear from site?

[Teresa W]

Hi,
I have some older macros I've downloaded, and going back to look up the documentation I cant find them anymore.
   
    Is is there a macro graveyard somewhere I can go to?
    Have they become embedded in the IJ source?
    Can I use the retired macro as part of method for a publication if there is no longer general access?

Thanks, Teresa
