I like to work sometimes at my school and I need to use some fonts that aren't on the machines here. Unfortunately the C:// has restricted access and I am unable to install any new fonts on there without admin permission.
Is there any way to use some other drive to read fonts?

Copy the fonts you want to use to a USB memory or so. When at school before you start any application double-click on the fonts to open them and then minimize. The fonts are now available to most applications until you close them.

Only on Windows versions prior to Windows 7 or Windows 8

Then hopefully the PCs at school are old ones

That's highly probable

Yet, there is always a way out

boot on your own system on a live usb key

Would the school Admin allow changes in the boot sequence

don't know.
sometimes, admins don't know what they do.

Go to the nearest hi-tech shop.
Try to change the BIOS password on the first computer you meet.
I'm sure you can brick it...

I think I would prefer the Hungarian solution

You could embed the font in an MS Word document on a computer that doesn't have installation restrictions, attach the document to an e-mail addressed to yourself, then open the e-mail and download the attachment at the school. This assumes that the font(s) you want to use allow embedding. You can only embed one font per document.

I wrote a tutorial on embedding in post #7 of this thread: http://www.dafont.com/forum/read/78124/why-won-t-this-font-work-when-i-try-to-make-it-bold

I should have said before that I wanted to use the fonts in Photoshop instead of word. Do you know of any embedding mwthods similar to that?

Thanks for telling me though. Pretty useful
