I effed my signature :(

In all honesty HTML probably should be disabled altogether in signatures and anywhere else for that matter. If people want tables and fancy stuff then there should simply be bbcodes for them.
If an iframe can mess up the forum layout then I do not want to see a cross site scripting attack.

Please don't disable html. My sig would be less cute.
It might be possible to just disable the iframe and script tags.
