Onboard FTDI question

-

i use ftdi cable or bob program projects, particular 1 beneficial have built right on board.  board run @ 5 volts, atmega328p-au chip having uno boot loader on it.
    question is, in schematic of sparkfun's ftdi breakout board,  won't needing 3.3v anything, can remove c1 & sj2, , have net 'power' connect directly '5v'?
it seems correct me, thought another's thought might same me problem on custom made pcb.
thanks.

Indesign and MathType fonts

i having trouble getting indesign recognize mathtype fonts.  have been told move mathtype fonts on 2 indesign font folder.  copied mt-extra font file mathtype folder , pasted indesign font folder.  nothing changed.  indesign still gives me blank box after copy mt-extra font mathtype -->illustrator-->indesign.   guess need instructions on how transfer of fonts done correctly.  i'v looked @ install fonts manual indesign, not clear me on how it.  need utility fontexplorer this, or there other way.  what's weird working fine until had reinstall osx , reinstall cs3, font trouble started.  need toggle "activate-reactivate' adobe cs3 , don't know how close 20 max on this, worried that.  (i suspect because of note on forum might necessary).  thoughts appreciated. i'm using windows, advice may worth nothing...   1) shouldn't have deactivate id recognize fonts. 2) design science gives fonts away in type 1 , truetype flavors....
