Comments and Colour and spacing

Hey Vantage,

Struggled with the theme for a while, now I just love it. Just a few questions. Please forgive my ignorance if these question are pretty easy.

Comments – is there a way of informing those who have commented on my blog that I have responded? Or do I need a pluggin?

Colour – I am playing around with the colour in the customised area. I hit fonts then ‘content heading colour’ and have changed the colour once and I want to change it again and it wont let me. It wont even go back to the default colour. Am I missing something.

Spacing.

In my side bar I have my current posts displayed. However it does not look neat, it looks as if one topic runs into another. Instead of having enough spacing between two bits of information. Is there a way I can create more spacing between the two.

Thanks in advance. I hope I have explained myself well enough for you to understand.
