Time Delay and Signatures

Hey DoomWorld guys, can you reduce the time delay between posts to about 30 sec? I know it's to prevent spamming, but I think that 2 minutes is a little too long. And how come the signature obeys some ASCII guidelines AND some HTML guidelines. I have a really cool .sig I use on Usenet and it screws up here because the spaces are reduced. Can you change some of this?

The font used for the forum is not a fixed-width font, e.g. the spaces aren't the same width as the individual characters, so your lovely usenet signature won't work. However, and I speak for a number of people here, the first time you read a large signature perhaps, its funny, but after that it just gets very irritating.
