Yes, i've read about this, and i think that it's worth logging too 
much data than not enough...

I've looked at opencellid.org website, and couldn't find any 
information concerning the database, how can a user access the data 
for example...

That's a good point, but for example, yesterday evening i've uploaded 
lot of data (about 5 hours sampling every 10 seconds, while moving by 
boat along the coast), and now i would like to reuse these data, 
exploit them, plot them, ... with existing web application or by 
writing my own tool, the API offered by cellhunter doesn't really fit 
my needs that's why i want to have a look at OBM's API.

Do you know how often CH is imported into opencellid, and how often 
opencellid are imported into OBM?
