Hi I am interested can i use signature space for advertising site which i want and if i can why i cant upload image is that because of my forum level?
You can advertise anything in your signature but image is not allowed evwn for high rank members. If you want to put a design in your signature you can use BBcodes instead. For your rank you limited to a certain number of characters and you can put a clickable link in your signature.
Colors are available when you reach full member, size once you are a sr. member and a background color once you are a hero and up.
