Yes I tried that before while experimenting.
I got lazy and just create a 'user_data' field to store some form data
without creating an actual field for each one.
Well it worked just fine and danady until I needed to do a search for a
particular value.
I then had to pull ALL the data, deserialize and search that data.
What a nightmare. But I did learn some new algorithms in the process.
I suppose sometimes it is our failures that teach us the best.
