I played it regularly for a bit some months ago. Had a good time on it.
The crafting limit is as such;
Free Members can queue up 1 item for crafting at any one time.
A member who has purchased (with money) the special market currency coins [Called G1 (GamersFirst) credits] can queue up 3 items at any one time. (I don't think you have to spend any of the points on items, but I may be wrong).
Becoming a subscriber grants you access to 20, 30 or 40 queue slots, depending on the package you choose.
Once your subscription ends, I presume that the queue slots drop back down to 3.
I'm not 100% sure on that though, as I never went subscriber.
But purchasing some of their premium currency and spending them got me the 3 slots. This was like £1.99 I think for the absolute minimum necessary, compared to the £7.00~ of subscription.
3 slots aren't many though, so if you're planning on making big crafting things, it'll be very awkward.
If you're building vehicles, it's also a nuisance. Since each part takes an hour, you can end up having to return every 3 hours to start something new to craft.
If you're a subscriber and have the higher limit, you can queue them all up overnight and come back the next day, since crafting will also carry on while you're offline.
