The bottom of the fork leg can turn independant of the upper tube. Not a problem.
"Fork Alignment" is really just making sure the two tubes are perfectly parallel. All this means on our bikes , to add to Hypers statement, is you put the axel in and tighten it all down...then loosen up the pinch bolts and then re-torque them. This allows any flex to to be relieved.
Some times the forks get "tweaked" meaning they get a slight twist to them, usualy after a fall. The wheel seems to point opposite the way the top part of the tubes seem to be facing. A quick shove the other way holding the tire still should fix it.
Lastly there is front fork allignment to the rear wheel. Given the design of our bike there ain't much one can do to adjust that, and it usualy falls under "rear wheel alignment" not "fork" alignment.
As how to check the first one...just assemble the forks leaving out the springs, install the front wheel , axle , tighten everything down..."relax" the pinch bolts as described above , and with help from someone else, slowly lift the wheel up and down making sure it does not bind anywhere. This is very important to do when installing a fork brace, but given the limited amount of travel our forks have, it's a bit difficult to feel anything out of whack. Then all that should be left is installing the fork springs, spacer, fork oil and the fork "plug" and circlip.
The only fork alignment you really have to worry about is from the plate to your mouth.
