I want to add a group tab in
system > configuration > general > general.
This tab will contain a text area where the user will be able to modify the text.
This text area will be connected with the database. When the user modifies the text then it will also be modified in database.
How can I do that? I have already created a new group tab but how I can connect it with my model ??
