How To Create A Simple Opera Addon
Creating opera addons is easy..
first start by making a called config.xml and put this inside of it:
edit the above text as you want it.... can use a fake email address if you want to 
Save it and create 2 images icon64.png which has to be 64x64 pixels and icon18.png which has to be 18x18 pixels
next create a file called index.html
you can change the width and hieght to what ever size you need it ;)
next create a file called popup.html
Now You have finished saving all your files into the same place...
if you want to just test it out at first you can just drag the config.xml onto opera and it will add your addon to the toolbar
(remember to right click on your addon and refresh if you make any changes to it.)
now to create the opera addon for others to use:
highlight all the files by either dragging your mouse around them or pressing Ctrl A if there is no other files in there that shouldn't be there.
then right click and send it to a zip file ..
Make sure you zip all the files together (do not put the folder containing the files into the zip)
once done rename the zip file to MyfirstAddon.oex
(if cant rename the format (zip to oex) search google "how to show file formats")
next drag it onto your opera and install it and make sure it works before sending it out to everyone
