I've never had a mod list in my sig. Nobody cares to see that crap under every single post I make.
If you want to reference your mods or pics of your car, just post a link in your sig for people to click on. Posting pics in threads that are relevant to the subject at hand is fine as well, or even creating a thread to show off your car. It just clutters up the site if everybody had a picture or avatar though.
Thanks for your compliance. /ubbthreads/images/graemlins/hsugh.gif
