Yes, you can always apply/ask to be an affiliate.
2 How do I apply?
Please use the cbox.
3 Are there requirements?
Not really, I don't like to exclude anyone. BUT I do prefer active-ish affiliates that stop by to say hi every now and then. I understand going on hiatus (as I have to do that myself from time-to-time).
4 We're affies but my link is not on your site???
TELL ME. I may have lost it while revamping T_T'
