Also, and to reiterate, by pledging
now (rather than at the end); you are helping the project to get front page attention on the KS site, which would mean more coverage for users that may otherwise not know about FPSC at all. Waiting till later will not help that occur.
To also reiterate another misconception; you will have
nothing taken out of your account until (and only if it is a go)
December 1st. So if you won't have the money for another couple of weeks; you can still pledge
now, without shelling out a dime. You can also simply pledge a
single pound right now, and amend your pledge at a later date (before the 1st of December); that will get us closer to front page coverage as well.
Don't let this opportunity slip by. It's possible that the project may go forward without the funding; but it won't happen in the time-frame that it would otherwise, if at all.
