Q: Registration lasts for how long?

[ND-]

I got the $20 paypal deal,
But even with the extra $5, it's worth it. Just the fact that your input is worth a big more if you're a registred user (or so I assume) is also worth it.

A lot of softwares doesn't have much of support, with ffxp, you can even "talk" to the author himself on the boards.
