Well, firstly you will need a Paypal account if you do not link back to us - so that you can pay for the link, otherwise:
For the Resource directory:
A website url (website address). Site / Company Name, a brief description of the site/company and some idea of what categories the Link should appear in
For the front page:
A small banner (not larger than 100x100) with a URL to link to, OR Site/Company Name, followed by a brief description, and then a website url to link to.
Please note: Space on the front page is limited, and so we may not always be able to offer you a space there.
