Good suggestion

[promarcos]

suggestion:
create a file to save the texts.

The signs could load the texts, the classic form, not where the text is a sing to another.
but could be done, used the two forms

sample file:
texts:
'1 ':
line1: &1this
line2: &2&lcool
line3: * form *
line4: edit sign
'2 ':
line1: &1more
line2: &2&lcool
line3: * form *
line4: edit commands

So in the game, the admin could just load the text typing something on the board:
eg

%FText [id]

and the plate would load the text.

This would be a form, to edit a large number of signs, at the same time, anywhere, without the need of being logged.
