Reply To: Submit button size and font

Take a look around line 2895 in your css for this (since you’re using the blue skin) –

.epik-blue button, .epik-blue input[type="button"], .epik-blue input[type="reset"], .epik-blue input[type="submit"], .epik-blue .sidebar .enews-widget input[type="submit"], .epik-blue a.button.small, .epik-blue a.button.medium, .epik-blue a.button.large, .epik-blue .circle {
    background: none repeat scroll 0 0 #054E86;
}
