what happens if more that 1 accounts try to run on the same box?

Better to begin with EFF.

Here goes again:

I've downloaded 0.7.5 new (from nxtcrypto) deleted the previous version, started from fresh, blockchain downloaded.
After a minute or so the above messages start appearing. Deleted the nxt_db folder, but again after a minute those messages start appearing.
I don't think I'm on a fork, because all my transactions show up, even the forged block from the day before yesterday.

What's going on? I want to be absolutely sure I don't lose any NXT and I want to do some transactions.
Could someone please assist me (in non-technical wording, okay technical is okay, just not programming deep-into-nxt stuff)  

same here...

IIRC, each node analyzes the known graph and assumes the longest chain as the correct one.

pls could anyone provide a basic info about client "Nxs" Like 3 sentences about it, maybe even 2 pictures.

Come from Beyond split the unclaimed coins between Pouncer, klee and neer.g; committees with spending authority over them have yet to be finalized. James jl777 has sole spending authority (with the exception of sending it to himself) on the three other accounts I am responsible for, since these were all started by private donors to support James' efforts.  

Here's the link to the consolidated treasurer's spreadsheet for the six ongoing funds.  Total amount in these is around 12.3 million NXT.  We're still getting it on a standardized format.  The four treasurers have implemented a system between us to obtain passwords to each other's accounts if any of us become incapacitated.

I personally am hoping to get on the infrastructure committee.  Official thread for selecting the committees is here:

Salsacz also has sole spending authority on an earlier marketing account.  The spreadsheet for that is:

In following all the posts here, it seems we are now getting to the point where real world use is coming to the forefront. Since NXT is not really best at micro-payments, but higher staked goods and services, so a TV show I watched peaked my interest. The name of the show is Gem Hunters http://www.travelchannel.com/tv-shows/gem-hunt/video

The basic concept is these individuals search other countries for gem stones to purchase and bring back to the US to sell. One interesting thing I noticed was the issues they continually had with currency, attaining, exchanging and safe guarding. Now I am quite sure most of the show is quite exaggerated, as most reality TV is these days, however, the fact of the matter is the gem trade world wide is a cash business for the most part and has never had a true alternative. I'm sure we can see the issues with walking around Zambia with $100,000 USD or any other fiat for that matter.

I imagine gem traders exchanging goods via a smartphone app and Nxt as the back end. I'm sure this may sound a bit far fetched, however, I just want to think outside the box for a moment and see if anyone else can think of similar business segments that have similar challenges.

NXS is actually not a client but an alternative web interface for the default NRS web app.
