Ya know...thinking about this, I may have come up with a solution...
Why not just have one profile field...or just a user editable box, so a user can enter data, link it...then go to a new line and repeat the process for each item they'd like to add.
You could then take the data they entered and add it to the ajax menu.
For instance...
I'm using this Quick Reply box...and I can enter whatever I want for my System Specs...
Compaq Presario SR5507F
Iris8-GL6
Next Item
Next Item
And so on and so forth...
Then just parse this info into the menu...wouldn't that work?
