Forum OpenACS Improvement Proposals (TIPs): TIP#106 (Approved) Add long text datatype for apm parameters
This makes it easier to edit long parameter values by providing a textarea on the parmaeter page instead of a text box.
That's it, its pretty simple.
The database check constraint will add another option "text" and the parameter-add/edit forms will show a new option in the dropdown.
I aleady have this implemented including a database upgrade to replace the check constraint for acs-kernel.
I vote "yes", especially since you've already done the work!
