**Deadlines**

Each conference announcement contains several special dates, which are deadlines for different sorts of activities connected to this conference (those dates are also published at the conference Internet site).

First of al it is a deadline for submitting papers. Normally it should be sent approximately 6 month before the conference start date, so it can be reviewed, correctly formatted and published into the proceeding (as the proceeding is normally distributed on the conference) before attendees will arrive to the conference. No articles will be considered to be included into the conference after this deadline.

Secondly, it is a notification date. That is a date when organisers must inform authors whether their articles where accepted or not. If the paper was accepted then there could be some remarks that you probably will like to address submitting the final version. If it is rejected then you could post that paper again to some other conference hoping that other reviewer will understand and value your ideas much more. So, this date is very important planning what will be the next conference you will submit this article to :).

Thirdly there is a deadline to submit a final version of the paper. After that date no changes can be included into the paper, so, for example, all mathematical mistakes cannot be fixed any longer and if such will be there then the paper will be incorrect forever.

*Less important, but still presented deadlines are a date to register to attend the conference by, deadline for payments etc.*

Finally there are conference dates, i.e. deadline by which you should arrive to the conference place and presumably have a talk in front of other attendees.
