Sorry for the ~1 of "downtime" that occurred - a typo I made in a file managed to take the whole site down for about 45 seconds - the time for me to notice it, find the file causing the problem, and restore it with a backup.

As for the upload script, it's close to being done, though I could use a few suggestions for it. All input is now secured (before any input was allowed, which could cause problems on the info page) and a few other changes were made to fix a few PHP notices. I should be able to finish most of the personalized build stuff tomorrow, so if anyone wants to test it, let me know in the comments.
