Conference offices

You can plan a conference by yourself, but you cannot conduct it alone: you need some assistance. You can obviously ask your postgraduate colleagues for help, but if you do not get any positive support, try to turn to your own home institution (or, to the institution that is going to house the conference), since many academic institutions offer this kind of service through a central conference office. You can delegate any duty from the early stages, but some help becomes absolutely essential when the conference starts, since at that stage you will not be able to deal with everything by yourself.
