Well I posted on this subject on the Modify group already, as they are the ones probably the most interested in it...
I have released my JavaScript file, that contains almost all the functions I use on my Multiply site : smilies, quotes, Bible quotes, info boxes, scheme menu, etc...
You can find out how to get the file and use it on the HOWTO file I have made for the purpose.
Enjoy, and send me your comments!!
