ignore new lines in signatures

[jamie]

Hi,

Does anybody know of a simple hack that would just ignore new lines in signatures,

ie if they put

I

R
E
A
L
L

L
O
V
E


it would just ignore all the new lines and show the signature as something like

I REALLY LOVE


Also (I am now pushing it!) if this is possible would a more advanced version be able, ie so that they could only have 4 new lines ( <br> ) and after this all new lines are ignored,


thanks
