is there any way to show off the serendipity logo in the blog

or at least make it more discrete

since size and color are not very friendly and some of my costumers are finding it annoying

i don't like it myself specially in dark backgrounds

it glows in an unlikely way

You can do it on the published website. Log in as admin then go to Blog Admin. On the left menu, there is 'Configure Plugins'. You can remove several plugins showing on your website here.
